(a) Fabrication process of graphene-electrode pentacene FETs. (b) Output characteristics of graphene-electrode pentacene FETs (channel length: 100 μm). Inset: microscopy image of graphene-electrode pentacene FET device. Scale bar: 1 mm. (c) Transfer characteristics of graphene-electrode pentacene and Au-electrode pentacene FETs at a fixed VD of −90 V (channel length: 100 μm). (d) Contact resistances RC of graphene and Au electrodes, normalized by channel width W (1500 μm).
