EDS分析是利用元素的特征X射线，而氢和氦原子只有K层电子，不能产生特征 X 射线，所以无法进行成分分析...
Energy-Dispersive X-Ray Spectroscopy (EDS) - ScienceDirectELSEVIERCharacterization in Silicon Processing
能谱的全称是:Energy-dispersive X-ray spectroscopy 国际标准化术语: EDS-能谱仪 EDX-能谱学 相关知识点: 试题来源: 解析 EDS 根据国际标准化术语,“EDS”对应能谱仪(设备名称),而“EDX”对应能谱学(学科领域)。提问主要涉及能谱技术的命名恰当性问题。在仪器设备层面,“EDS”是标准缩写,特指具体的分析...
电镜一般有两种,扫描电镜(SEM)和透射电镜(TEM)。如果EDS用在SEM上,则是用来分析样品表面的元素;若是用在TEM上,则可以分析样品内部的化学组成。 EDS是用高能电子(SEM的话大概5-20keV,TEM的话60-300keV)轰击样品(也有不用电子而用质子或X射线的),样品中原子里的基态(groundstate)电子吸收入射电子的能量被激发到...
