Graphene/silicene heterostructure and vertical FET: (a) Band structure. Green and red represent graphene and silicene components, respectively. (b) ( E , k x )-dependent transmission probability. Inset: Dirac cones of graphene (green) and silicene (red) in the miBZ. (c) Schematic plot of single-gated heterostructured vertical FET. (d) Transfer characteristics at v ds = 0.2 V.
