✦ Synopsis


Low coverage adsorption of antimony on the silicon (1 1 3) surface is investigated by X-ray standing waves. The measurements in three non-collinear Bragg geometries yield a dominant single adsorption site which is compatible to an antimony-adatom site. The coordinates of this site are determined with high precision and the strain induced on the Si substrate surface is discussed.

The chemisorption of one monolayer Ag atoms on an ideal Si(1 0 0) surface is studied by using the self-consistent tight-binding linear muffin-tin orbital method. The adsorption energies (E ad ) of different sites are calculated. It is found that the adsorbed Ag atoms are more favorable on C site (fo
