Abstract
Auger-electron spectroscopy (AES) has developed to a major tool for chemical identification and for characterization of solid surfaces. As first emphasized by Lander[1], it can also be used a spectroscopy for gaining information on occupied electron states and their interactions. However, AES gives a far less direct picture of the occupied states than does, for example, angle-resolved photoemission spectroscopy. Owing to the broad selection rules, Auger spectra sample large classes of one-electron states, and the interpretation is also complicated by possible effects of the interparticle interaction and of the surface. I will here try to convince the reader that Auger spectra from sp-bonded materials can nevertheless be fairly well understood using conceptually rather simple models. I will, however, also emphasize the need of realistic evaluations of such models in order to verify that they contain the correct physical mechanisms. A large part of this review will be focused on recent, yet unpublished work by the Lund group.
