Abstract

The sensitivity of the energy-loss near-edge structure (ELNES) in reflection electron energy-loss spectroscopy (REELS), used in parallel with reflection electron microscopy (REM) and diffraction is shown to provide information on modifications of the TiO2(110) surfaces under strong electron irradiation. The ratio of the sharp peaks in the ELNES is strongly dependent on the oxidation state of the surface. The ELNES obtained from REELS reflects the variation of the surface density of states (DOS) of a few atomic layers. The quantitative analysis of the chemical compositions in the TiO2(110) surface before and after being irradiated by the electron beam indicates a relative decrease of the oxygen component, which corresponds to the reduction of the oxide.
