    Carbon nanotubes (CNTs) are emerging as promising platforms for organic thermoelectric (TE) materials. However, the poor stability of n-doped states often presents a problem for the long-term operation of p–n junction TE modules. In this study, we synthesized a cross-linked organic superbase, 2TBD-C10, as a dopant to create n-type CNTs that are resistant to air, heat, and humidity. When comparing the stability of 2TBD-C10-doped CNTs with those doped by a conventional superbase (TBD), we found that the enhanced stability could be attributed to the unique molecular structure of 2TBD-C10. This structure aids in effective adsorption on the CNT surfaces through multiple points, reduces volatility because of increased molecular weight, and suppresses water adsorption owing to the presence of hydrophobic alkyl chains. The results of our study demonstrate that tailoring the primary molecular structures of dopants can remarkably improve the stability of doped states in CNTs. The stable n-type materials were integrated into all-CNT TE modules, achieving good-to-excellent performance (power output of approximately 35 μW from a temperature difference of approximately 65 °C), making them suitable for powering wireless sensors and green light-emitting diodes.

    Abstract Internet of Things (IoT) is crucial for a sustainable society from the viewpoints of optimization of energy consumption and using timing, thus aiding reduced CO2 emissions. Traditional power supply methods such as batteries are impractical for driving the trillions of sensors that future systems will likely utilize for collecting extensive environmental information. Thermoelectric power generators that enable direct heat‐to‐electricity energy conversion are considered a promising power supplying technology without maintenance because thermal energy is a ubiquitous energy source. This study develops a new class of thermoelectric modules using redox‐free electrolytes—‐thermally chargeable supercapacitor (TCS)—‐with extremely high thermoelectromotive force, generating over 2 V from a temperature difference of ≈65 °C without requiring a DC‐to‐DC converter. Additionally, using a voltage detector is demonstrated to be a versatile and efficient toolbox for the charge management of TCS. Optimization of the circuit comprising the TCS module with the ultrahigh open‐circuit voltage and voltage detector enables the automatic charging of a large capacitor, which intermittently powers different devices such as a beacon, LED, piezo speaker, and motor with the desired frequency. This approach represents a significant step toward sustainable energy in the context of low‐grade thermal energy harvesting and optimized energy consumption through IoT.

    Abstract Developing efficient and stable carbon nanotube (CNT) doping techniques and elucidating their chemistry is essential for their further implementation in electronic and energy devices. Here, protonic acids and lithium salts are employed as p-type inducers and stabilizers of the doped state, respectively. Leveraging the electron-withdrawing capability of protons, protonic acids can easily induce heavily p-doped states in CNTs. Anionic species from the acids attach to the positively charged CNTs to achieve charge compensation. Introducing lithium salts with bulky, charge-delocalized anions to the p-doped CNTs results in an anion replacement driven by the free energy gain. The newly formed complexes demonstrate outstanding thermal stability in air, enduring a temperature of 100 °C for over a year. The chemical hardness of the applied anion effectively explains the difference in stability of the doped CNTs, indicating that the doping process and its stabilization can be understood and controlled through complex chemistry.

    1D organic semiconductor nanostructures have attracted considerable attention; however, only a few studies are conducted on p–n junction organic semiconductor 1D nanostructures. Herein, p‐ and n‐type and p–n junction phthalocyanine (Pc) nanorods are grown in the out‐of‐plane direction of a substrate via vacuum deposition using typical organic semiconductors with copper phthalocyanine (CuPc) as the p‐type semiconductor and copper octafluorophthalocyanine (F8CuPc) and copper hexadecafluorophthalocyanine (F16CuPc) as the n‐type semiconductors. p–n junction Pc nanorods are fabricated via the continuous deposition of F8CuPc and F16CuPc onto CuPc nanorods. Fourier‐transform infrared spectroscopy reveals that the Pc molecules in the nanorods are perpendicularly aligned, with their molecular planes oriented toward the longitudinal direction of the nanorods. The local current–voltage properties of the nanorods are measured using conductive atomic force microscopy. The hole mobility in the CuPc nanorods is 10 times higher than that in the CuPc thin films. The p–n junction properties of F8CuPc/CuPc nanorods are evaluated.

    Wearable piezoelectric micropumps may contribute to improving drug delivery in the field of medicine. Poly(vinylidene fluoride/trifluoroethylene) (P(VDF/TrFE)), an organic ferroelectric polymer, is a desirable material for fabricating the piezoelectric layer of medical micropumps owing to its biocompatibility and flexibility. However, a large voltage is required to drive the micropumps because the piezoelectric response of P(VDF/TrFE) is small compared with that of inorganic materials, such as lead zirconate titanate. In this study, thin films (P(VDF/TrFE)) are focused that can reduce applied voltage and improve the flexibility of entire actuators. In addition, actuators sealed with poly(monochloro‐paraxylene) (Parylene C) are considered, which has excellent chemical resistance, flexibility, and biocompatibility. The calculated piezoelectric constant |e31| of the fabricated P(VDF/TrFE) thin films is 42 mC m−2. A large deformation of 1 mm is observed in the fabricated cantilever‐type actuators sealed with Parylene C when a voltage of 160 V is applied. Furthermore, the vibration of the actuators by the reverse piezoelectric effect on the water surface is observed. It is indicated in these results that a low voltage can safely drive P(VDF/TrFE) thin‐film piezoelectric actuators sealed with Parylene C in medical micropumps.

    Abstract An isotropic thermo‐electrochemical cell is introduced with a high Seebeck coefficient (Se) of 3.3 mV K−1 that uses a ferricyanide/ferrocyanide/guanidinium‐based agar‐gelated electrolyte. A power density of about 20 µW cm−2 is achieved at a temperature difference of about 10 K, regardless of whether the heat source is on the top or bottom section of the cell. This behavior is very different from that of cells with liquid electrolytes, which exhibit high anisotropy, and for which high Se values are achieved only by heating the bottom electrode. The guanidinium‐containing gelatinized cell does not exhibit steady‐state operation, but its performance recovers when disconnected from the external load, suggesting that the observed power drop under load conditions is not due to device degeneration. The large Se value and isotropic properties can mean that the novel system represents a major advancement from the standpoint of harvesting of low‐temperature heat, such as body heat and solar thermal heat.

    pi-Conjugated dendrimers, with unique optical properties, have the potential to be used as light-harvesting antenna in organic solar cells and photodetectors. Here, the broadband absorption and light-energy transfer in a phenyl-core thiophene dendrimer, Ph-(7T)(3), have been investigated using quantum calculations and absorption, photoluminescence, and excitation spectroscopy. The broadband absorption of the highly branched Ph-(7T)(3) macromolecule could be attributed to multiple pi-conjugations in Ph-(7T)(3) (due to phenylthiophene and thiophene oligomers with different numbers of thiophene units). The divergency of the wavelengths between photoluminescence and excitation light indicated that the multiple pi-conjugating system exhibited various modes of excited-state relaxation, which could explain the light-energy transfer from the core to the thiophene dendrons. The fluorescent quantum yield and lifetime of this molecular system are also presented.

    Abstract Normal alkanes are among the simplest molecules that can be studied in physical chemistry. However, there is still more to learn about their liquid-to-gas phase transition characteristics, especially in vacuo. Here, we investigated the evaporation behavior of 12 different normal alkanes using thermogravimetry, both in air, and under reduced pressures (5000 to 10−2 Pa). The reduced pressures lowered the evaporation-onset temperatures of the normal alkanes. The evaporation-onset temperatures at 1 Pa were linearly correlated with the chain lengths (molecular weights). Furthermore, we found that the reduced pressures enabled the effective distillation of binary mixtures of normal alkanes because of the differences in the evaporation-onset temperatures. It was empirically determined that distillation (isolated evaporation of one of the binary mixture components) was achieved at ∼1 Pa when the chain of one of the alkanes was 30% longer than that of the other.

    Abstract The preparation of air and thermally stable n-type carbon nanotubes is desirable for their further implementation in electronic and energy devices that rely on both p- and n-type material. Here, a series of guanidine and amidine bases with bicyclic-ring structures are used as n-doping reagents. Aided by their rigid alkyl functionality and stable conjugate acid structure, these organic superbases can easily reduce carbon nanotubes. n-Type nanotubes doped with guanidine bases show excellent thermal stability in air, lasting for more than 6 months at 100 °C. As an example of energy device, a thermoelectric p/n junction module is constructed with a power output of ca. 4.7 μW from a temperature difference of 40 °C.

    Multipoint detection of the structural deformation of a pulsating 3D heart model was conducted using a flexible piezoelectric sensor array with a poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] thin film sealed with biocompatible parylene C. The piezoelectric signals detected from the sensor array attached to the 3D heart model were correlated with an electrocardiogram signal. These piezoelectric signals can be converted into the compressive stress applied to the flexible sensors by the pulsating motion of the 3D heart model. The experimental results mean that the contraction force, generated by the heart muscle (i.e., myocardium), can be directly evaluated. The different output voltages depending on the location were obtained from each sensor, indicating the possibility of a real-time detection of the irregular motion of the heart and the early detection of ischemic heart disease, which leads to the loss of local contractile force in myocardial tissue.

    The feasibility of using organic thermoelectric devices to power sensors for different applications is a critical area of interest for researchers. Organic semiconductors possess lower thermoelectric performance than their inorganic counterparts, however, this can be compensated for by certain advantages, such as their light weight, low fabrication costs, and low fabrication temperatures. For practical applications, they face competition with Li-ion batteries, which are known for their high energy densities and long lifetimes. Thus, in addition to having a suitable corresponding power output, ideal organic thermoelectric devices require excellent stability. In this study, such a perspective was examined via primarily focusing on recent studies of organic thermoelectric devices and, particularly, their practical applications. The impact of contact resistance on device performance has been discussed, together with suggestions of certain promising device structures for organic thermoelectric devices. Experimentally, it was confirmed that light and compact organic thermoelectric devices with a size of similar to 10 cm(2) should be sufficiently suitable to power sensors. Moreover, these devices were confirmed to operate under natural cooling conditions without a heat sink, thus showing excellent stability for >70 days under continuous working conditions at 100 degrees C.

    Imidazolium chloride salt was demonstrated as a novel water-processable, strong base-free electron dopant for single-walled carbon nanotubes (SWCNTs). By thermoelectric evaluation and various photoelectron spectroscopy analyses associated with the comparison of the redox potentials, the valence change of the anion (Cl-/Cl3-) was presented as a possible mechanism for electron injection into the nanotube conduction band. The obtained n-type SWCNT films presented good thermoelectric power factor exceeding 100 mu W m(-1) K-2, nearly identical to that of the original p-type film.

    Thermoelectric power generation from waste heat is an important component of future sustainable development. Ion-conducting materials are promising candidates because of their high Seebeck coefficients. This study demonstrates that ionic hydrogels based on imidazolium chloride salts exhibit outstanding Seebeck coefficients of up to 10 mV K-1. Along with their relatively high ionic conductivities (1.6 mS cm(-1)) and extremely low thermal conductivities (similar to 0.2 W m(-1) K-1), these hydrogels have good potential for use in heat recovery systems. The voltage behavior in response to temperature difference (stable or transient) differs significantly depending on the metal electrode material. We evaluated the electrode-dependent temperature sensitivity of the double layer capacitance of these hydrogels, which revealed that the thermally induced polarization of ions at the interface is one of the main contributors to the thermovoltage. Our results demonstrate the potential capability for ion and metal interactions to be used as an effective baseline for exploring ionic thermoelectric materials and devices. The developed thermoelectric supercapacitor exhibits reversible charging-discharging behavior under repeated disconnecting-connecting of an external load with a constant temperature difference, which offers a novel strategy for heat-to-electricity energy conversion from steady-temperature heat sources.

    pi-Conjugated dendrimers are emerging platforms for molecular-based photonics and electronics. Herein, we demonstrate thiophene dendrimers as new thermoelectric (TE) materials with large Seebeck coefficients through chemical charge-carrier doping, conducting film preparation, and TE transport evaluations (electrical conductivity and Seebeck coefficient). Complementary characterization with absorption, photoelectron spectroscopy, and molecular calculations reveals that the highly degenerate frontier molecular orbital energy levels derived from the highly branched and symmetric molecular structures of the dendrimers play an important role in the anomalously large Seebeck coefficients based on Mott's equation. With the recent rapid progress in the technologies for synthesizing pi-conjugated dendrimers and molecular designing flexibilities, our results propose a novel strategy for exploring new TE materials.

    We report a new near infrared (NIR) absorbing dye, phenyl-fused dibenzo-BODIPY with benzo[1,3,2]oxazaborinine rings (PhBODIPY), for organic photodiode (PDs). PhBODIPY can be deposited on the substrates without thermal decomposition and its deposited film is amorphous state with high thermal stability. The deposited film showed broadband absorption in the wavelength range of 600-1000 nm. The NIR-OPD with PhBODIPY film demonstrated a detectivity (D*) of 7.41 x 10(11) Jones under NIR light irradiation at a wavelength of 820 nm. The D* improved to 1.70 x 10(12) Jones by co-deposition of 1:1 (w/w) PhBODIPY:fullerene (C-60). The photocurrent was maximized under light irradiation at a wavelength of 694 nm, corresponding to the absorption wavelength of H aggregated state of PhBODIPY molecules. The formation of Haggregated state is important to further improve OPD characteristics. (C) 2020 The Japan Society of Applied Physics

    Perpendicularly oriented vinylidene fluoride oligomer thin films with six molecular layers were poled during vacuum evaporation (in situ poling) using a micro-gapped comb-like electrode, and their pyroelectric characteristics were investigated. The extent of polarization achieved with in situ poling performed by applying a low electric field (7.7 MV m(-1)) is the same as that achieved by conventional post-poling with the application of a high electric field (>100 MV m(-1)). Despite using a film with a few molecular layers, the in situ poled sensor showed pyroelectric response without the use of an infrared ray absorption layer; voltage sensitivity of 198 V W-1 was obtained, which is much higher than that of the post-poled sensor (similar to 16 V W-1). The improvement in sensitivity is attributed to the amount of charge injected during the poling treatment. (C) 2019 The Japan Society of Applied Physics

    Quantitative analyses of photodegradation for three fluorene-based photovoltaic polymers, poly[2,7-(9,9-dioctyl-fluorene)-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (APFO3), polyfluorene (PFO), and poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT), were conducted to understand the molecular origin of photostability for polymers. The Fourier transform infrared spectra of the polymer thin films varied with irradiating white light at 100 mW cm(-2) irrespective of their molecular architectures. The absorption peaks corresponding to alkyl side chains in the fluorene unit decreased, whereas those for polymers that did not comprise carbonyl groups increased. This spectral variation indicates that alkyl side chains in the fluorene unit decompose when the molecular structure of fluorene changes to that of fluorenone. The reaction rate constant of the formation of C=O bonds for APFO3 was 1.64 x 10(-5) s(-1), lower than those for PFO (7.59 x 10(-5) s(-1)) and F8BT (2.64 x 10(-5) s(-1)), under light irradiation at 30 degrees C. The photostability of the polymers was improved by designing a donor-acceptor type molecular architecture incorporating photostable electron-deficient benzothiadiazole units with photo-unstable fluorene units.

    Herein, we report the thermophysical properties of dichloro-[2,2]-paracyclophane (the parylene C dimer) under vacuum. The parylene C dimer is the raw material used to prepare parylene C, a thin film known for its useful dielectric and barrier properties. In order to investigate the first step in the synthesis of parylene C by chemical vapor deposition, the sublimation, evaporation, and melting behavior of the parylene C dimer was examined by simultaneous thermogravimetry/differential thermal analysis (TG-DTA) under vacuum and at atmospheric pressure. The evaporation onset temperatures, saturation vapor pressures, and the phase-transition temperatures of the parylene C dimer were quantified by TG-DTA at various pressures. The evaporation and sublimation temperature easily decreased by increasing the level of vacuum, while the melting temperature was independent of the external pressure. Our results led to the construction of a pressure-temperature phase diagram. (C) 2020 The Japan Society of Applied Physics

    Flexible piezoelectric devices with poly (vinylidene fluoride-trifluoroethylene) thin films were fabricated, and directly monitoring of the heart state and piezoelectric power generation were investigated using the pulsating 3D heart model. By attaching the flexible piezoelectric devices to the 3D heart model, the piezoelectric responses corresponding to the pulsation of the right and left ventricles were observed and reflected the status of heart. The maximum output voltage was obtained in the front of the right ventricle of the heart model. The output energy, which caused from piezoelectric effect, improved linearly with the increase of the device area, and was estimated to be approximately 8 nJ mm(-2) per heartbeat.

    We show that conducting polymer Poly (3,4-ethylene dioxythiophene)/poly (styrene sulfonate) film could be an ideal electrode in thermo-electrochemical cells, which shows a low charge transfer resistance. Using ferricyanide/ferrocyanide as an electrolyte, the Poly (3,4-ethylene dioxythiophene)/poly (styrene sulfonate) based thermo-electrochemical cell could be used to drive light-emitting diodes array. The conducting polymers also show the advantage of hybrid insoluble redox couples such as Prussian blue analog materials, making it easy to measure the temperature-dependent redox potential. By a combination of proper redox couples, the thermally regenerative electrochemical cells could realize. The power could generate during the environmental temperature change.

    Poly(3,4-ethylenedioxythiophene) (PEDOT) was fabricated via vapor-phase polymerization (VPP) of the monomer 3,4-ethylenedioxythiophene (EDOT) with FeCl3?6H(2)O melt as the oxidant at the EDOT vapor?FeCl3?6H(2)O melt interface. Highly doped VPP-PEDOT films were formed on the oxidant melt surfaces. The morphological changes and decrease in the doping level at the VPP-PEDOT film surface were attributed to slower oxidant transport up to the surface during VPP. The doping level of VPP-PEDOT was higher when the oxidant melt was used compared to when the oxidant thin film was employed, and the maximum doping level was twice of that obtained in our previous work.

    In this study, semiconductive elastomers composed of homopolythiophene with disiloxane moieties were developed. The crosslinked molecular structure in the polythiophene elastomers was introduced by dicumyl peroxide, one of the typical peroxide crosslinking reagents. The elastomers were produced through a hot-pressing process above the melting point of the polythiophene. Stress-strain curves that included tensile tests and cycle loading-unloading tests defined the crosslinked polythiophenes as elastomers. Their electrical conductivities were evaluated by two-point measurements under nondeformation and uniaxial deformation states. The results indicated that the concentration of crosslinking reagents greatly influenced the mechanical and electrical properties of crosslinking polymers. With the addition of the crosslinking reagent in concentrations from 2.5 phr to 10.0 phr, elongation at break decreased largely from 95% to 51%, while excellent elastic recoveries were observed. In the electrical resistivity measurements, all the crosslinking polymers possessed high stability of electrical properties against elongation.

    The low volatility of ionic liquids (ILs) is one of their most interesting physico-chemical properties; however, the general understanding of their evaporation dynamics under vacuum is still lagging. Here, we studied the thermodynamics of IL evaporation by employing thermogravimetry (TG) measurements under vacuum. The thermodynamic parameters of ILs, such as the evaporation onset temperatures, enthalpies, entropies, saturation vapor pressures, and boiling points were quantified by analyzing the TG data. The obtained evaporation enthalpies (110-140 kJ mol(-1)) were higher than those of typical molecular liquids, and the entropies (>88 J mol(-1) K-1) suggested that they are exceptions of the Trouton's rule. The obtained Clausius-Clapeyron equations demonstrated that the saturation vapor pressures of ILs only depend on temperature. Further, we derived the empirical equation for estimating the upper limit temperature of the liquid phase of IL under given external pressures. Using the evaporation behaviors of referential normal alkanes and charge-transfer complex and the evaporation entropies of the ILs, the vaporized IL structure was thermodynamically modelled. The ILs were found to evaporate as ion pairs, instead of as individual ions or higher-ordered cluster structures. By comparing a series of ILs with various cations and a fixed anion, it was found that the IL evaporation dynamics under vacuum is strongly and systematically affected by their chemical structures, charge balances between the cations and the anions, molecular weights, and the higher-ordered structures including polar and non-polar regions. Our concept, measurement method, and equation can be extended to other ILs and low-volatile liquids under vacuum, and help with the design of ILs with higher thermal stabilities.

    Carbon nanotubes (CNTs) dispersed in water by sonication with surfactants are used as printing inks. However, surfactants are usually electrical insulators that remain on the prepared CNT films, reducing their conductivity. While evaporation by annealing is an effective removal process, it is usually performed at high temperatures (180 degrees C) in air, making it inapplicable for printing on common plastic substrates. This work demonstrates a vacuum annealing process for evaporating surfactants. Poly(oxyethylene) 4 lauryl ether (Brij L4)-a nonionic surfactant-was utilized. Its evaporation behaviors (thermodynamics and kinetics) were analyzed by thermogravimetric (TG) analysis and infrared (IR) spectroscopy. The TG measurements confirmed that the evaporation onset temperature under vacuum (51.0 degrees C) was lower than that in air (148.7 degrees C). The IR results revealed that similar to 100% Brij L4 was removed by annealing under vacuum at 130 degrees C. The desorption energy of the surfactant from CNTs was calculated from the activation energy results to be about 10 kJ mol(-1); this value is about a half to one order of magnitude smaller than those reported for other surfactants. This energy would allow adequate adsorption interactions for the surfactant to stably disperse the nanotubes, but is sufficiently small to allow easy removal of the surfactant by thermal treatment. The electrical resistance of the vacuum-annealed CNT thin film dramatically decreased compared with that of the film annealed in air. Therefore, this process can be used for fabricating flexible printed electronics with CNTs.

    This paper describes an evaluation of ionic liquids (ILs) as potential electrolytes for single-layered light-emitting devices with good emission performance. As optoelectronic devices continue to grow in abundance, high-performance light-emitting devices with a single emission layer are becoming increasingly important for low-cost production. We show that a simple technique of osmosing IL into the polymer layer can result in high luminous efficiency and good response times of single-layered light-emitting polymers, even without the additional stacking of charge carrier injection and transport layers. The IL contributions to the light-emission of the polymer are discussed from the perspectives of energy diagrams and of the electric double layers on the electrodes. Our findings enable a faster, cheaper, and lower-in-waste production of light-emitting devices. (C) 2018 The Japan Society of Applied Physics

    Here, we studied the charge-carrier modulation of single-walled carbon nanotubes (SWCNTs) via poly (vinyl acetate) (PVAc) doping and dedoping under ultraviolet (UV) light irradiation with the aim of pairing several p- and n-type SWCNTs as thermoelectric (TE) elements. The Seebeck coefficient of the SWCNTs was first made negative by doping with PVAc and then made positive again through UV-induced PVAc dedoping. A possible TE module configuration and the process for its fabrication are proposed, wherein prints and photopatterns can be obtained without the use of additional electrodes. Our findings enable the fabrication of fine TE modules using simple materials and techniques. (C) 2017 Elsevier B.V. All rights reserved.

    Thin films of poly(3,4-ethylenedioxythiophene) (PEDOT) were fabricated via the vapor-phase polymerization (VPP) of the monomer 3,4-ethylenedioxythiophene (EDOT) with FeCl3 center dot 6H(2)O as the oxidant. The doping level and electrical properties of the VPP-PEDOT films were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and electrical conductivity measurements. The VPP of EDOT was observed by in situ ultraviolet-visible (UV-Vis) absorption spectroscopy. The results showed that highly doped PEDOT films were formed in the initial stages of VPP, and the doping level increased as the reaction proceeded. The doping level eventually decreased because of the limited amount of the oxidant. Therefore, it was concluded that the doping level of VPP-PEDOT thin films could be changed depending on the initial amount and supply of the oxidant. The thermoelectric properties of the as-synthesized VPP-PEDOT films were also studied, with the aim of applying them as an energy harvester and/or a temperature sensor.

    Single-walled carbon nanotubes (SWCNTs) are important candidates for flexible and non-toxic thermoelectric (TE) energy-harvesting devices because they have large Seebeck coefficients, good flexibility, and inkjet printability onto plastic substrates. Here we describe the successful n-type conversion of intrinsic p-type SWCNTs by polymer-dopant charge transfer. The negative Seebeck coefficients of the polymer-doped SWCNTs were strongly related to the highest occupied molecular orbital levels of the polymer, demonstrating that the polymers were electron donors for the nanotubes and that the doping level could be controlled by modifying the functional groups. The n-type SWCNTs obtained using oxygen-abundant polymers, such as poly(vinyl alcohol) and poly(vinyl acetate), exhibited the largest negative Seebeck coefficients and high stability under ambient conditions lasting for at least 3 weeks. Printed and folded p-and n-type SWCNTs on flexible substrates showed efficient TE voltage improvements. Our findings enable the easy, low-cost preparation of air-stable n-type SWCNTs, permitting the exploitation of SWCNTs as flexible and eco-friendly TE materials.

    Crystal growth of Alga was achieved in an ionic liquid by vacuum vapor deposition. Alq(3) crystals of several tens of microns in size showed beautiful hexagonal morphologies, different from previous reports. The successful crystal growth can be explained by the enhanced migration of Alga molecules and moderate supersaturation within the ionic liquid. The Alq(3) crystal showed unique optical properties, such as a waveguide and blue-shift of the photoluminescence spectrum.

    The tuning of the Seebeck coefficient of a single-walled carbon nanotube (SWCNT) film was achieved by using the dipole field of a ferroelectric polymer. The Seebeck coefficient was positive under an up-poling dipole field, but negative under a down-poling dipole field, whereas the control remained positive. This tunable behavior can be explained by selective carrier injection and accumulation, which was confirmed by the temperature dependence of electrical conductivity. Connecting p- and n-type SWCNT films tuned by dipole fields to create a pi module resulted in a significant improvement in output voltage owing to the temperature difference between the two.

    We have investigated the thermoelectric power of single-wall carbon nanotubes (SWCNTs) with an ionic liquid (IL). The SWCNT/IL films showed simultaneous increase in electrical conductivity and the Seebeck coefficient compared with the pristine SWCNT. No thermoelectric power was observed for the IL. The X-ray diffraction pattern and impedance diagram showed a unique behavior with the concentration of IL, which implies that the interaction between the SWCNTs and IL enhances the thermoelectric power of the SWCNTs. As a result of the simultaneous increase in these parameters, the power factor exhibited a 10-fold increase. (C) 2016 The Japan Society of Applied Physics

    The crystal growth and unique morphological changes of organic semiconductor rubrene, fabricated by ionic liquid (IL)-assisted vacuum vapor deposition, were investigated. The texture and structure of rubrene films strongly depended on the thickness of IL films on substrates, namely, three-dimensional dendrites in 3D-ILs, two-dimensional microfibrils in 2D-ILs, and two-dimensional spherulites in 0D-ILs. The growth of two-dimensional spherulites would be promoted by the supersaturation of ILs, minutely controlling the rate and total amount of rubrene deposition. The growth mechanisms of rubrene fabricated by IL-assisted vacuum vapor deposition were different from that of the conventional one in terms of the nucleation and growth modes.
