Auger electron spectroscopy (AES)
Auger Electron Spectroscopy (AES) is a technique used to analyze the surface composition of materials at a very small scale. It works by directing a beam of high-energy electrons onto a surface. This causes certain electrons in the material to be knocked out of their atoms. As other electrons fall into these vacant spots, they release energy in the form of Auger electrons. By measuring these electrons, scientists can determine the types and amounts of elements present on the surface, helping to understand material properties and behaviors in fields like materials science and nanotechnology.

Auger Electron Spectroscopy (AES) is a technique used to analyze the surface composition of materials at a very small scale. It works by directing a focused beam of electrons onto a sample, causing the emission of secondary electrons from the surface. These emitted electrons carry information about the elements present in the material. By measuring their energy levels, scientists can identify the specific elements and their concentrations in the top few nanometers of the sample. AES is valuable in fields like materials science, chemistry, and nanotechnology, helping researchers understand material properties and behaviors.
