在HR XPS图谱中,对比纯Sn3O4,Sn3O4/PPy的Sn 3d、O 1s结合能降低,说明PPy与Sn3O4间有较强的的相互作用,Sn3O4/PPy异质结中的C 1s被分解为几个明显的峰,部分峰位的形成与Sn3O4和PPy的复合有关。 Fig. 5. (a) XPS s...
NbSnhigh resolution4d band structureXPS valence band spectra of Nb 3Sn, Nb and Sn have been obtained under high resolution. The 4 d band structure in the Nb 3Sn spectrum is similar to that seen in Nb metal.doi:10.1016/0038-1098(76)90681-5H. H?chst...
All XPS spectra were collected using a PHI Versaprobe II equipped with a multichannel hemispherical analyser and aluminium anode X-ray source operating at 100 W with a 100-μm beam scanned over a 1.4-mm line across the sample surface. A dual-beam charge neutralization system was used with an...

The 3d XPS spectra and LMTO calculations indicate a strong hybridization of the f orbitals with conduction band and the interatomic hybridization which causes the large charge transfer between atoms. We have also observed the correlation between the electronic structure near Fermi energy and the ...
