Auger Electron Spectroscopy (AES)
Starts at P9,700/sample (P7,760 student rate)
Auger Electron Spectroscopy (AES) is an analytical technique used to study surfaces. Secondary electrons that are emitted as a result of the Auger process are analyzed and their kinetic energy is determined. The identity and quantity of the elements are determined from kinetic energy and the intensity of the Auger peaks. Auger electrons have energies ranging from 50 eV to 3 keV. At these low energy values, electrons have a short mean free path. The escape depth of Auger electrons is therefore localized to within a few nanometers of the target surface, giving AES an extreme sensitivity to surface species.
