Measurement of the 2p XPS spectra of 4d metals: Nb to Sb
1998年3月1日 · XPS spectra of the 2s core level of Ag, Pd, Rh, Ru, Mo and Nb. The main peaks have been aligned at zero binding energy. The spectra were excited with a Ti anode and contain the contributions from both the Ka~ and K~2 excitations. the corresponding XPS spectra, whose final states, after all, involve the initial state of the Auger transi- tions.
XPS谱图都包括些啥? - 知乎 - 知乎专栏
eds与xps的不同点: 1) 基本原理不一样: 简单来说,XPS是用X射线打出电子,检测的是电子;EDS则是用电子打出X射线,检测的是X射线。 2) EDS只能检测元素的组成与含量,不能测定元素的价态,且EDX的检测限较高(含量>2%),即其灵敏度较低。
基础理论丨一文了解XPS(概念、定性定量分析、分析方法、谱线 …
XPS, 全称为X-ray Photoelectron Spectroscopy(X射线光电子能谱), 早期也被称为ESCA (Electron Spectroscopy for Chemical Analysis),是一种使用电子谱仪测量X-射线光子辐照时样品表面所发射出的光电子和俄歇电子能量分布的方法。 XPS可用于定性分析以及半定量分析, 一般从XPS图谱的峰位和峰形获得样品表面元素成分、化学态和分子结构等信息,从峰强 可获得样品表面元素含量或浓度。 XPS测表面还是体相? XPS是一种典型的表面分析手段。其根本原因在 …

We report on the influence of different anodic films on surface leakage current for InAs1−xSbx (x = 0.195) high operation temperature (HOT) photodiode grown on GaAs substrate. The electrochemical...
XPS studies of the intermediate valence state of Yb in (YbS)
2008年9月1日 · This paper presents the X-ray photoelectron spectroscopy (XPS) spectra of Yb 4f, 5p, 4d and 4p together with Cr 2p and S 2p spectra. It is found that Yb 4f, 5p, 4d and 4p structures are spread in a wide energy region due to a mixed valence state and strong exchange and Coulomb interaction among a core hole and localized 4f electrons.
