Abstract Electron transport in a model nanodevice consisting of a combination of graphene, silicene, and molybdenum disulfide coupled by van der Waals bonds is studied within the framework of the density functional theory in the local-density approximation and method of nonequilibrium Green functions. The volt–ampere and dI/dV characteristics and transmission spectra of the nanodevices are calculated. It is revealed that the combination of silicene and molybdenum disulfide forms a new nanosystem with metallic properties manifesting themselves in its electron transport characteristics. It is shown that the graphene–MoS2–silicene hybrid nanostructure has rectifying properties due to the formation of the Schottky barrier, while steps of Coulomb origin appear in its volt–ampere characteristic at a positive voltage.
