Abstract:
New metallic structures in the system of graphene and molybdenum disulfide layers with embedded rhenium atoms, in which the graphene layer is rotated by $30^\circ$ to the molybdenum disulfide layer and the Re atom either substitutes the molybdenum atom in the MoS$_2$ layer or is located between the layers mainly interacting with three sulfur atoms and six carbon atoms, are examined. In the latter case, a high electron density of states has been found in the Fermi level, which indicates a high metallicity of the graphene$30^\circ$-(Re)-MoS$_2$ bilayer in comparison with other bilayer structures considered earlier. All proposed structures are energetically stable. Possible applications of the studied bilayers have been considered as well.
