Auger Lineshapes of Solid Surfaces - Atomic, Bandlike or Something Else?

Abstract

A simple model is presented to predict the level of localization (i.e., localization onto an atomic, bonding lobe, molecular, or band orbital) of the two and three hole final states in Auger lineshapes. In the spirit of the Hubbard model, the extent of localization is predicted from the one- and two-center Coulomb interaction potentials and the relevant valence bandwidths. Results from the model are compared with experiment for the N KVV lineshapes from NaNO3, and the S and Si L23 VV lineshapes from Li2SO4 and SiO2. These lineshapes exhibit a wide range of localization consistent with the model. (Author)
