催化材料研究:XPS在催化材料的研究中用于分析活性位点的化学状态,以及在催化反应过程中的变化。 电子结构研究:通过XPS测量的价带谱(Valence Band Spectrum),可以研究材料的电子结构和能带结构。 材料表面改性:在材料表面处理(如等离子体处理、化学气相沉积等)后,XPS可以用来评估处理效果,如表面官能团的变化。 腐蚀和防护...
Collect XPS valence band spectrum to distinguish between SnO and SnO2. Interpretation of XPS Spectra Sn3d region has well-separated spin-orbit components (Δmetal=8.4eV). Peaks have asymmetric peak shape for metal. Loss features are observed to higher binding energy side of 3d3/2 spin-or...
4d 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...
The x-ray photoemission valence band spectra of NbC have been measured and are compared with the x-ray emission spectra and with the results from band structure calculations. This comparison leads to a large enhancement of theC2 p photoabsorption cross section (atℏω=1,487 eV) compared to...

Acquire C1s, C KLL, and valence band regions. Maximizes ability to distinguish between sp2and sp3carbon. C KLL acquisition conditions: Pass energy=100eV, step size=0.5eV, 100 scans, scan range binding energy=1,190eV-1,246eV. Charge neutralization may be required, especially for functi...
It was found that the half-width of the O Kα band decreases somewhat but that of the XP valence-band spectrum increases when going from h-WO3 to CuWO4, however the energy positions of the maxima and of the centres of gravity of the O Kα band remain constant for the above compounds...
(c) a difference spectrum between the measured data in (a) and the fitted curve; (d) difference between (a) and (b). [61]. 2.3.4 Valence band XPS All examples of XPS described above involve core-level photoelectron excitation (e.g. S 2p core-level XPS spectra, as opposed to S ...
