Electrons ejected from the surface are energy filtered via a hemispherical analyser (HSA) before the intensity for a defined energy is recorded by a detector. Since core level electrons in solid-state atoms are quantized, the resulting energy spectra exhibit resonance peaks characteristic of the ...
XPS的应用及举例解析 X射线光电子谱(XPS)X-rayPhotoelectronSpectroscopy 冷永祥西南交通大学材料科学与工程学院 XPS引言 引言 X射线光电子谱是重要的表面分析技术之一。它不仅能探测表面的化 学组成,而且可以确定各元素的化学状态,因此,在化学、材料科学及表 面科学中得以广泛地应用。表面几个原子层进行分析X射线...
Peak intensity d-spacings and lattice parameters Fix l (Cu ka)=1.54 dhkl = 1.54/2sinhkl Note: Most accurate d-spacings are those calculated from high-angle peaks. For a simple cubic (a=b=c=a0) a0 = d 30、hkl /(h2+k2+l2) e.g., for BaTiO3, 2220=65.9o, 220=32.95o, d220 =...
