Abstract
A self-consistent electronic-structure calculation of alkali-metal overlayers on the semi-infinite jellium surface is performed within the local-density-functional theory combined with the embedding-potential method. The results obtained confirm that the adatom charge state is very insensitive to coverage (Θ), and also that the hybridization between adatom and substrate states plays an important role in the adatom-induced dipole and its Θ dependence.Keywords
