第五章 X-射线光电子能谱(X-ray Photoelectron Spectroscopy (XPS) ESCA) 一 概述 表面分析技术 (Surface Analysis)是对材料外层(the Outer-Most Layers of Materials (100 ?))的研究的技术。包括: 1 电子谱学(Electron Spectroscopies) X-射线光电子能谱 XPS: X-ray Photoelectron Spectroscopy 俄歇能谱 AES:...
XPS是用已知固定波长(即固定能量)的X射线(X-ray)轰击样品,把样品中原子里的电子撞出来,然后测量撞出电子的动能以及拥有某一动能值的电子数。这样我们可以得到一个能谱图。通过测量入射X-ray与图中峰值对应的动能之差,我们可以确定样品原子中电子的结合能(bindingenergy)。然后可以查一查这个结合能与哪种元素电子的...
