Engineering Physics Annotation << Back STEPWISE BEHAVIOR OF THE CONDUCTIVITY IN THE EPITAXIAL GRAPHENE ON QUANTUM METAL FILM Z.Z. ALISULTANOV, E.Kh. ISRAPOV Within the Davydov model, we investigated the static conductivity of epitaxial graphene formed on the surface of the size-quantized metal film. We used an approach based on the Kubo formula for conductivity. It is shown that in the vicinity of the energy levels, the conductivity varies jumpwise. We give a qualitative explanation of obtained effect. Key words: graphene, conductivity, Kubo formula, Green functions. Contacts: E-mail: zaur0102@gmail.com Pp. 21-25.
