Introduction
Scanning Electron Microscope (SEM) is a type of an electron microscope that images the sample surface by scanning with an electron beam. The electrons interact with the atoms that make up the sample-producing signals, such as Secondary Electron (SE), Backscattered Electron (BSE), and characteristic x-rays that contain information about the sample's surface morphology, topography, composition, and other properties.
