UPS spectra also have strong angular dependence for the excited electron, which can give information about band structure in the k space. The light incidence angle and polarization and, the plane of incidence (with respect to the surface, crystal lattice) determine the A for the exc...

contribute to the spectra, so the valence band structure of NbO2 and Nb2O5 can be con?rmed from ultraviolet photoelectron spectroscopy (UPS). By comparing the UPS with density of state results, the electronic structure of NbO2 and Nb2O5 can be distinguished from each other, and then the...

Theoretical analysis of ARUPS of a Si(100) surface at room temperature 来自 Semantic Scholar 喜欢 0 阅读量: 16 作者:K Inoue,M Nakayama,H Kawai 摘要: ARUPS spectra of a Si(100) surface with disorder perpendicular to the dimer row are studied by the tight-binding method for the ensemble ...
A ligand effect was observed for CO adsorbed at Cu sites by comparing UPS spectra for CO on pure Cu and CO adsorbed at Cu sites on the alloy. The CO emission features for CO adsorbed at Cu sites on the alloy are shifted by ~0.6 eV compared to CO on pure Cu. Strong adsorbate-...
Our XPS and UPS spectra show that the energy bands of PdO are narrow ( 2–3 eV), moreover the energy shift of the core levels (| ΔE F B| = 2 eV) is important : these results suggest that the correlations between the d electrons may be important in PdO. 展开 ...
