Electron energy loss spectroscopy (EELS) is the use of the energy distribution of electrons that pass through a thin sample to analyze the content of the sample and create images with unique contrast effects. EELS instrumentation is typically incorporated into a transmission electron microscope (TEM) or a scanning TEM (STEM). These microscope types use high energy electrons (60 – 300 kV ...
2.2 EELS的原理. 在非弹性散射电子中，存在一些具有一定特征能量的俄歇电子，其特征能量只与物质的元素有关，如果在试样上检测这些俄歇电子的数目并按照能量分布，就可以标定物质的各元素组成。. 如果其特征能量不仅与物质的元素有关，而且与入射电子的 ...
