摘要：

A 2.2% lateral and 8.5% vertical lattice expansion, as compared to bulk Ag(111), has been found in a high resolution surface X-ray scattering study for the underpotentially deposited Ag bilayer on Pt(111). The larger-than-bulk lattice constants are unusual for an incommensurate adlayer. It presumably arises from a considerable charge transfer from Ag to Pt, which results in an additional repulsion among the adatoms. (C) 1998 Elsevier Science B.V.
