Auger electron spectroscopy

Auger electron spectroscopy (AES) is a surface analysis technique used to study materials at the atomic level. It works by bombarding a sample with high-energy electrons, causing the ejection of electrons from the atoms in the surface layer. The emitted Auger electrons carry specific energy signatures that correspond to the elements present in the material. By measuring these energies, scientists can identify the elemental composition and chemical states of the surface. AES is valuable in fields like materials science, nanotechnology, and semiconductor research, where understanding surface properties is crucial for developing advanced technologies.
