Schematic showing the steps of the DI water SPeeD graphene transfer method.
(a) CVD graphene is grown on Cu substrate. (b) PMMA is spin-coated on the graphene grown on Cu/Pt substrate. (c) Kapton tape is pressed on PMMA with a teflon roller. (d) The stack is immersed in DI water at 90°C. Water penetrates between graphene and Cu substrate and separates them. (e) Kapton tape with PMMA and graphene on it is pressed against the target substrate and heated for 40 minutes at 140°C. (f) The PMMA on the target substrate is removed with acetone and RTA.
