High-resolution Auger electron spectroscopy (HRAES)

High-resolution Auger Electron Spectroscopy (HRAES) is an analytical technique used to identify and analyze the surface composition of materials. It involves bombarding a sample with a focused electron beam, which causes atoms on the surface to emit characteristic electrons called Auger electrons. By measuring these electrons' energies with high precision, scientists can determine the types and quantities of elements present at the surface. This method provides detailed surface chemical information with excellent spatial and energy resolution, making it valuable for studying material surfaces, thin films, and coatings in various scientific and industrial applications.
