A study was conducted to analyze the transfer of graphene from one substrate to another for creating flexible, transparent graphene devices with high field effect mobility. A single layer graphene is a two-dimensional semi-metallic material composed of one atomic layer of carbon atoms. It shows band structure suppresses carrier backscattering, resulting to high carrier mobility. It can allow extension of printing technology to a single atomic layer. The transfer printing method can be used to transfer graphene between SiO2/Si and plastic substrates, forming a complete graphene field-effect transistor with gate on flexible, transparent substrates. Mechanical exfoliation was used to create atomically-clean graphene sheets for producing devices. The thickness and morphology of graphene were measured using an atomic force microscopy (AFM). Results show that transport properties of the graphene exhibit the non-universality of minimum conductivity.
