SURFACE-STRUCTURES OF METALLIC MONOLAYERS ON METAL CRYSTAL-SURFACES

The structures of adsorbed metals on single crystal surfaces of other metals are reviewed and tabulated. Most of the adsorbates of over 100 systems studied form ordered surface structures that may undergo changes as the coverage in the monolayer is increased. At low coverages the adsorbate and substrate surface structures are closely related, which indicates the predominance of the absorbate-substrate interation in determining ordering. At higher coverages there are more complex ordering characteristics.
