SEM Scanning Electron Microscope is a device used to study the structure at a molecular level In this technique an electron beam is used which consists of high energy electrons These electrons are called primary electrons Backscattered electronsBSE are reflected back after elastic interactions between the beam and the sample Secondary electronsSE however originate from the atoms of the sample they are a result of inelastic interactions between the electron beam and the sample Auger electrons are originated from the core of the sample which also releases energy BSE comes from deeper regions of the sample while SE originates See Answer
