Abstract

Preferential sputtering of compounds and alloys results in a compositional change of the surface and near surface region compared to the bulk composition. This effect can be caused by different mechanisms and the resulting concentration profiles should be different. For segregation-induced preferential sputtering an enrichment in the outermost layer and a loss in the sublayers of the segregating compound is expected /1/, in contrast to collision dominated systems.
