After dithizone immobilization (Fig. 1, lower, right), the TEM image shows a darker-greyish color compared to left-side image indicating the existence of dithizone component that coats the...

做过透射电镜（tem）测试的小伙伴有过这样的经历，拿回来一堆图片，图都认识，就是读不懂意思。 或者在阅读文献的过程中，看到大片的TEM图片，也是头大。

Usage of Bragg diffraction to create contrast in TEM image. It’s simply a special form of amplitude contrast where the scattering occurs at special (Bragg) angles. Bragg diffraction is...

Use crystallographic software that can generate diffraction patterns and stereograms to help you navigate your sample, and ensure you indexing is consistent. A Kikuchi map is incredibly useful too for deducing how your sample is oriented (PTCLab is open source and produces nice maps)

In the transmitted-light microscope, variation of intensity within an image is caused by differences in the absorption of photons within different regions of the specimen. In the case of a TEM, however, essentially all of the incoming electrons are transmitted through the specimen, provided it is suitably thin.

In this chapter, we study a general description of the linear imaging theory of high-resolution electron microscopy, which was started by Scherzer (1949) and completed by Hanszen (1971) using the concept of “transfer function in optics. The theory is applicable to.
