▎ 摘  要

Two modes of graphene-substrate interaction have been considered: a weak van der Waals bond and a strong covalent bond. The Lennard-Jones potential and Harrison bond-orbital method are used in the former and latter cases, respectively. Analytical expressions for the electron-phonon interaction constants, which contain only two parameters (binding energy E (B) for graphene and a substrate and distance d between them) have been obtained. The constants have been calculated for metallic, semiconductor, and dielectric substrates.
