Water-free transfer method for CVD-grown graphene and its application to flexible air-stable graphene transistors

Abstract

Transferring graphene without water enables water-sensitive substrates to be used in graphene electronics. A polymeric bilayer (PMMA/PBU) is coated on graphene as a supporting layer for the water-free transfer process and as an excellent passivation layer that enhances device operation.
