In particular, characterization of VB spectrum obtained with a takeoff angle of less than 24° is effective to obtain VB spectrum only from the passive film on Ti. The property as n‐type semiconductor of the passive film on Ti is probably higher than that of rutile TiO2ceramics.Eda,...
Therefore, the band gap narrowing of the Cu doped materials results in shifts of the VB and CB that is not identical for the nano and micron sized cases. Since the Cu2+ content is highest in the ZC1200 sample and the band gap is smallest for this sample, the narrowing of the band ...
The emission and reflection spectra of ZnO have been investigated in the intrinsic region and the data have been interpreted in terms of the wurtzite crystal band structure. Free-exciton emission is observed for the first time. Both the Γ5 and Γ6 state excitons associated with top valence ban...
He I, He II and Al Kα photoemission spectra of the valence band of α-MnS are reported. The He I and II spectra were obtained on a crystal platelet (bounded by (111) planes), the Al Kα spectrum was from a polycrystalline sample. The strong dependence on hν of the photoionization...
Although STS measurements do not directly probe the momentum dependence of the electronic spectrum, some information can be adduced from the nature and size of the band gap seen in the differential conductance spectrum (Fig. 4(d)). Since the tunneling current depends on the overlap surface ...

The simple MO theory of H2 gave a better band length, but a poorer dissociation energy, than the VB theory. Which was better? Both could be improved-the MO theory by the inclusion of interaction between more configurations ( electronic, not geometrical !) of the same symmetry : and the ...
The valence band spectra for the two pyroxenes are rather similar, and quite different from the VB spectra of quartz and olivines. The dispersion of the pyroxene VB spectra is intermediate between the VB spectra of quartz and olivines; the valence band spectrum of pyroxenes are more dispersed...
XPS study of the valence band spectrum of amorphous Fe-B alloys XPS spectra of Fe 3s and Fe 3p levels and Fe 3d valence band of amorphous iron-boron alloys were measured as a function of boron concentration over the ran... M.,Matsuura,and,... - 《Solid State Communications》 被引量:...
