Abstract. In the paper, a theoretical study of the transport properties of double walled graphene with the different structure of the layers relative to each other has been carried out. The band structure of the system and the variation of conductivity depending on the different configurations of graphene layers have been revealed. The study was carried out with using the molecular orbitals in the framework of the π-electron approximation. The metallic conductivity and also its weak dependence on the direction in the crystal have been found. A weak dependence of the conductivity on the mutual arrangement of the graphene layers has been revealed.
Key words: graphene bilayer, electric field, conductivity, nanoribbon, Hubbard model.
