Abstract: Simple model schemes for taking into account the dipole–dipole repulsion of adatoms in submonolayers on three- and two-dimensional semiconductor substrates are proposed. General expressions for determining the contributions of the band and local states to the charge transfer between the adsorbed layer and the substrate as a function of the degree of coverage of the substrate with adatoms are presented. Analytical estimates for some special cases are made.

Keywords: adsorption, charge transfer, dipole-dipole repulsion, band and local states.
