Abstract
The Ag/MgO(100) interface has been studied by EXAFS. At room temperatu re, in agreement with previous investigations, silver at low coverage is shown to form a two-dimensional layer at the MgO(100) surface. EXAF S data demonstrate that the lattice parameter of the silver overlayer is expanded so as to fit the MgO parameter to give rise to an interfac e having (100)(Ag)parallel to(100)(MgO) and [100](Ag)parallel to[100]( MgO) orientation. Interface Ag atoms are atop the oxygen atoms of the MgO(100) surface at a distance of 2.53+/-0.05 Angstrom.
