From: Electron beam induced removal of PMMA layer used for graphene transfer
(a) Schematic of fabricating graphene FET devices based on the e-beam bombardment technique for removing PMMA layer used for transferring graphene. (b) Optical image of graphene FET devices with the part of PMMA layer removed by the e-beam processes (scale bar: 20 μm). (c) AFM image of a graphene FET device.
