During the past six years, the adsorption geometries of several rare gases in structures having several different symmetries on a variety of substrates were determined using low-energy electron diffraction (LEED). In most of these studies, a preferen

The adsorption geometry of Ag(1 1 1)–(√7×√7) R 19.1°-4Ar was studied using low-energy electron diffraction (LEED). This higher-order commensurate phase was produced by preadsorbing a small amount of CO in order to block the close-packed steps

The temperature dependence of the first three interlayer distances of the Ag(111) surface was studied by low-energy electron diffraction (LEED) over the temperature range 128K to 723 K. The first three interlayer spacings and the effective Debye temp

A dynamical LEED study of the (3×3) structure which forms upon coadsorption of K and O on Ni(100) indicates that this structure is comprised of one K atom and four O atoms per (3×3) unit cell. The K atom is adsorbed in a substitutional site, and su

The structures of five different submonolayer commensurate phases of Cs on Ag(111) have been determined by low energy electron diffraction (LEED). This paper presents the results of two of these studies: for the primitive (2 3 ×2 3 )R30° and ( 7 ×

Low-energy electron diffraction (LEED) measurements were made for N2 and CO adsorption on Ag(111) at temperatures (T) >25 K. The results indicate that at coverages up to a saturated monolayer, N2 and CO each forms a rotated incommensurate hexagonal s

The adsorption geometries for the primitive (3×3), (2×2) and ([Formula: see text] 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 occu

Low-energy electron-diffraction results from rare gases adsorbed on Ag(111) are presented. On the clean surface, the rare-gas overlayer lattices are always aligned with the substrate step direction, but when a small amount of a different adsorbate is

Rare gas (RG) coadsorption with submonolayer amounts of Cs or K on Ag(111) was studied using low-energy electron diffraction (LEED). A crossover in the alkali-RG interaction from repulsive to attractive was observed as a function of alkali species an
