What is SEM? An SEM is a type of electron microscope that uses an electron beam to scan the sample. The electrons that are backscattered, as well as the ones that are knocked of the near-surface region …

Thus, this document material is aimed at helping SEM users and future SEM users to understand the basics of the SEM, including the instrument princi-ples, specimen preparation and elemental analysis.

The types of signals that SEMs are working with the most would be SE, BSE and the X-rays that are used in XEDS(EDX) characterization. Thank you and good luck!
