Scanning Electron Microscope (SEM) is a high-resolution electron microscope that can be used for high-resolution imaging and chemical analysis of sample surfaces. The principle of SEM is to use the interaction between the electron beam and the sample surface to generate secondary or backscattered electron signals, which are detected and imaged through detectors. SEM has the advantages of high resolution, high sensitivity, high depth resolution, and chemical analysis, and is widely used in fields such as materials science, biology, geology, electronics, etc. View >>
