Abstract

Scanning tunneling microscopy studies of mixed domain p(2×2) and (√3×√3)R30° tin-platinum surface alloys are presented. It was found that the apparent height of Pt ensembles increases with a decreasing number of Sn next-neighbor atoms per Pt atom. This is explained by a reduction of the local density of states near the Fermi level at Pt sites due to the effects of alloying of Pt with Sn.
