Backscattered Electrons
Backscattered electrons are electrons that are reflected back after colliding with a material, often observed in electron microscopy. When a high-energy beam of electrons hits a surface, some of these electrons scatter back rather than passing through. This phenomenon provides valuable information about the material's composition and structure, as the intensity and energy of the backscattered electrons vary depending on the material properties. This technique is widely used in research and industry to analyze samples at a microscopic level, helping scientists and engineers understand the materials they work with.

Backscattered electrons are high-energy electrons that are deflected backward after colliding with a material’s atoms, often observed in the context of scanning electron microscopy (SEM). When a beam of electrons hits a sample surface, some of those electrons bounce back instead of passing through. This backscattering provides valuable information about the sample's composition and topography, helping scientists and engineers analyze materials at a microscopic level. Essentially, backscattered electrons help create detailed images and data that reveal the structure and properties of various materials.
