Introduction to Scanning Electron Microscopy
www.sjsu.eduFeb 01, 2005 · In scanning electron microscopy visual inspection of the surface of a material utilizes signals of two types, secondary and backscattered electrons. Secondary and backscattered electrons are constantly being produced from the surface of the specimen while under the electron beam however they are a result of two separate types of interaction.
