Abstract
Scanning tunneling microscopy studies of mixed domain p(2 x 2) and (root3 x root3)R30 degrees 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 ef fects of alloying of Pt with Sn. (C) 2000 Elsevier Science B.V. All rights reserved.
