Scanning Electron Microscopy (SEM) is a well suited tool for the examination of surfaces and structures on a micrometer or submicrometer scale. The achievable lateral resolution is about 1 nm. SEM micrographs show an extreme large depth of focus.

Integrated energy-dispersive x-ray microanalysers (EDX) allow chemical analysis of microscopic volumes for all elements with atomic number Z > 4 at a detection limit of > 0.1 weight%. The analysis of electron backscatter diffraction patterns (EBSD) provides information on crystal structures and -orientations. It can be used to describe the microstructure, determine the phase contents, grain size distributions, analyze deformation mechanisms or textures within the material.
