CVD Graphene transferring proccess. The schematic of the transferring procedure for fabricating large suspended graphene membranes. Suspended CVD graphene was fabricated using typical procedures, including polymethyl methacrylate (PMMA) spin-coating, backside graphene etching, copper foil etching, rinsing, and wet-transfer onto a perforated SiO2/Si substrate. After the PMMA/graphene membrane was thoroughly dried, PMMA was removed using the Inverted Floating Method.
