Figure 12
EDC images around (a) the O 1s core, (b) the Ti 2p core, (c) the valence band and (d) a kinetic energy of 694 eV, taken at room temperature with a photon energy of 753 eV. The images were measured by fixing the Z axis at 2 mm and scanning the Y′ axis from −2.5 to 1.5 mm [the black line in Fig. 11(b)] at intervals of 0.04 mm. The measured energy ranges correspond to the colored rectangles in Fig. 11(c). The white lines were obtained by integrating all photoelectrons emitted in the measured kinetic energy. All spectra were taken at room temperature with a photon energy of 753 eV (LHR). |
