透射电子显微镜(Transmission－electron－microscopy,－TEM)
透射电镜具有很高的空间分辩能力，特别适合纳米粉体材料的分析。其特点是样品使用量少，不仅可以获得样品的形貌，颗粒大小，分布以还可以获得特定区域的元素组成及物相结构信息。透射电镜比较适合纳米粉体样品的形貌分析，但颗粒大小应小于300nm，否则电子束就不能透过了。对块体样品的分析，透射电镜一般需要对样品进
Transmission－Electron－Microscope－(TEM)
所谓TEM，就是一个放大镜叠加了一台照相机。这台放大镜的放大倍数比较高，可高达一百万倍。当然，抛开分辨率谈放大倍数都是耍流氓，那么，TEM的分辨率有多高呢？答案是 it depends。一般来说，TEM的分辨率要在1到2个纳米，STEM更高，但是STEM得成像技术类似于SEM，但用的不是二次电子。我

如何通过透射电子显微镜（TEM）初步确定待测样品
束1. 选区电子衍射（selected area electron diffraction）： 判断样品的晶体结构，晶格常数，点阵应变等。通常需要结合X射线衍射来综合判断。但选区电子衍射的选区范围最小只能达到~200 nm。这主要是来自物镜像差的限制。现在前沿的技术是纳米电子微区衍射(Nanobea
