    Surface structural changes of Ti-doped diamond-like carbon (Ti-DLC) film exposed to a hyperthermal atomic oxygen beam were investigated using near-edge X-ray absorption fine structure (NEXAFS) spectroscopy using synchrotron radiation. The spectral shape of the C K NEXAFS spectrum of as-deposited Ti-DLC film resembled that of DLC film. After exposure to atomic oxygen, the spectrum resembled that of TiC powder. The sp(2)/(sp(2) + sp(3)) ratio of as-deposited Ti-DLC film decreased drastically by exposure to a hyperthermal atomic oxygen beam. On the other hand, the spectral shape in the Ti L NEXAFS spectrum of as-deposited Ti-DLC film resembled that of TiC powder and became similar to that of TiO2 powder after exposure to atomic oxygen. These changes are ascribable to the desorption of C atoms as CO and/or CO2 from Ti-DLC film due to the irradiation of atomic oxygen beam. On the other hand, oxidized Ti was not desorbed from the Ti-DLC film. As a result, the sp(2)/(sp(2) + sp(3)) ratio of C in the Ti-DLC film decreased, because residual C atoms were bonded to Ti atoms.

      Oxidation reaction efficiency of the embedded Si atoms in the diamond-like carbon (DLC) film was studied with a combination of the broad O-atom beam, high-speed chopper wheel and synchrotron radiation photoelectron spectroscopy (SR-PES). The high-speed chopper wheel converted the translational energy distribution of O-atom into spatial distribution on the DLC surface. High spatial and energy resolutions of SR-PES allow studying the difference in oxidation states of Si atoms in different translational energies. It was confirmed that the SiO2 was formed by the high-energy collision conditions of O-atoms, whereas sub-oxides are formed with the low-energy collisions. The efficiency of SiO2 formation at 9 eV-collision is evaluated to be 4 times greater than that at 2 eV-collision.
