Within the framework of the density functional theory in the local density approximation and the method of nonequilibrium Green's functions, electron transport in a model nanodevice consisting of a combination of graphene, silicene, and molybdenum disulfide interconnected by van der Waals bonds is investigated. Current-voltage, dI / dV characteristics, and transmission spectra of nanodevices are calculated. It is revealed that the combination of silicene and molybdenum disulfide forms a new nanosystem with metallic properties, which are manifested in its electrical transport characteristics. It is shown that the graphene-MoS2-silicene hybrid nanostructure has rectifying properties due to the formation of a Schottky barrier, and steps of Coulomb origin appear on its current-voltage characteristic at a positive voltage.
