Abstract

A simple model of the effect of an adsorbed submonolayer on the direct-current (dc) conductivity of epitaxial graphene formed on a semiconductor substrate, which takes into account the dipole-dipole repulsion of adatoms, has been proposed. It has been shown using the example of two limiting special cases that the adsorbed layer increases the dc conductivity of epitaxial graphene. Numerical estimations have been performed for the adsorption of atomic hydrogen and oxygen.
