By applying nonequilibrium Green’s functions in combination with density-function theory, we investigate the effect of the weak intermolecular interaction on electronic transport properties in a bilayer graphene nanoribbon device. The results show that a successive switch behavior can be realized by adjusting the weak π–π interaction between two graphene nanoribbon molecules. Moreover, rectifying behavior can be observed in such systems. The mechanisms for these phenomena are suggested.
