An experimental and theoretical investigation on the PL2,3VV Auger lineshape of the InP(110) surface is presented. A band-like picture provides a good description of the spectral features. In addition, deposition of one monolayer of Sb on InP(110) is shown to drive the surface atoms into an environment similar to that present in the bulk, so that a comparison between the PL2,3VV spectrum from the clean and Sb-covered sample allows us to discriminate between the surface contribution and the bulk contribution to this surface-sensitive Auger transition.

Abstract
An experimental and theoretical investigation on the PL2,3VV Auger lineshape of the InP(110) surface is presented. A band-like picture provides a good description of the spectral features. In addition, deposition of one monolayer of Sb on InP(110) is shown to drive the surface atoms into an environment similar to that present in the bulk, so that a comparison between the PL2,3VV spectrum from the clean and Sb-covered sample allows us to discriminate between the surface contribution and the bulk contribution to this surface-sensitive Auger transition.
