电子显微镜概述(1)电子显微镜包括以下三种类型的仪器:扫描电子显微镜:Scanning Electron Microscopy(SEM)用于微形貌观察、显微成分分析透射电子显微镜:Transparent Electron Microscopy(TEM)用于微结构分析、微形貌观察电子探针:Electron Probe Microscopic analyzer(EPMA)微区成分分析、显微形貌观察粉煤灰的SEM照片:从煤粉炉烟道气...
scanning electron microscopy(扫描电子显微镜,SEM):扫描电子显微镜是l 965年发明的较现代的细胞生物学研究工具,主要是利用二次电子信号成像来观察样品的表面形态、即用极狭窄的电于束去扫描样品,通过电子柬与样品的相互作用产生各种效应,其中主要是样品的二次电子发射。二次电子能够产生样品表面放大的形貌像。这个像是在...
Scanning electron microscopy principles Scanning electron microscopes(SEMs) use an electron beam to image samples with a resolution down to the nanometer scale. The electrons are emitted from a filament and collimated into a beam in the electron source. The beam is the...
