The satellite peak in the Cr 2p spectra originating from the plasmon﹍oss phenomena was found only for CrSi and CrSi2. The binding energy of Si 2p shifted, reflecting the silicide phases; the energy of CrSi2 and CrSi was 0.3 eV higher and lower, respectively, than that of elemental Si....
(a)XPS是表面分析方法,探测深度通常小于10nm,所以在需要结合离子源刻蚀进行深度分析,例如先用XPS测试表面信息,然后用离子源刻蚀移除表面,之后重复XPS测试和刻蚀过程。(b)离子源的刻蚀速率会采用标准样品进行测定,刻蚀的深度可以用刻蚀速率x刻蚀时间得到。但是需要注意的是,对于不同材料,刻蚀速率会有较大差别,特别是对于...
Both spectra were acquired from the same sample under the same conditions with the exception that the ejected electrons for the Ge 3d peaks are about 1200 eV more energetic that the Ge 2p electrons. The consequence of choosing to quantify based on one of these transitions is that the ...
We have measured Mn-2p photoemission spectra in Mn perovskites doped by two methods: La 1 xCa xMnO 3 and LaMnO 3+ δ. Intra- and inter-series comparisons reveal that the position and intensity of the Mn-2p satellite depend only on the level of doping, and that it can always be decompo...
