Abstract Atomic models for the ErSi 2 /Si(111) interface are proposed and studied with computed simulated images, which are compared with experimental HREM ones taken along The calculations were performed for ten different models of the interface. The study reveals the validity of two of those models. The atoms at the interface are at positions and distances compatible with the structures of silicon and the silicide. Evidence is also presented for the existence of other types of interfaces in the system.
