Simple model schemes for the account of the dipole-dipole repulsion in sub-monolayers on 3D and 2D semiconductor substrates are proposed. General expressions for the band and local states contributions to the charge transfer between adlayer and substrate are given in the function of substrate coverage with adatoms. Analytical estimations are fulfilled for the number of the specific characteristic cases.
Coulomb interaction in adsorption system is reduced to the short-range
repulsion of the electrons of adsorbed particle and substrate surface atom which are
considered as the surface dimer. It is shown that the account of such an interaction
leads to the increase of charge transfer between the dimer’s components and decrease of charge transfer between dimer and metallic substrate due to the
Fermi level variation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
