Significance and Use
Auger electron spectroscopy is often capable of yielding information concerning the chemical and physical environment of atoms in the near-surface region of a solid as well as giving elemental and quantitative information. This information is manifested as changes in the observed Auger electron spectrum for a particular element in the specimen under study compared to the Auger spectrum produced by the same element when it is in some reference form. The differences in the two spectra are said to be due to a chemical effect or a matrix effect. Despite sometimes making elemental identification and quantitative measurements more difficult, these effects in the Auger spectrum are considered valuable tools for characterizing the environment of the near-surface atoms in a solid.
