Abstract

The adsorption geometries for the primitive(3×3), (2×2)and ($\sqrt{3}\times\sqrt{3}{\rm R}30^\circ)$structures of K, Rb and Cs on Ag(111) have been determined using low-energy electron diffraction. In the lower-coverage(3×3)and(2×2)structures, the adatoms occupy fcc hollow sites, while in the$(\sqrt{3}\times\sqrt{3}){\rm R}30^\circ; structure they occupy the hcp hollow sites. The fcc hollow structures are accompanied by significant substrate rumpling. There is no significant coverage-dependent or site-dependent change in chemisorption bond length. However, there is a large coverage-dependent anisotropy of vibrational amplitude of the adatoms, with the parallel component as much as five times larger than the perpendicular component at low coverages.
