On the Dipole–Dipole Interaction of Atoms in the Layers Adsorbed on Three- and Two-Dimensional Semiconductors

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 lay...

Description
Summary: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.
