Wafer-scale synthesis and transfer of high quality monolayer graphene for nanoelectronics

Recent progress in synthesis of large area mono- or few layer graphene on copper catalyst[1] has enabled various fascinating sensor, optical and electrical applications.[2-4] The idea for graphene to be employed for next generation nanoelectronics, however, require high quality films with wafer-scale uniformity and low defect density. Here we report our progress on wafer-scale synthesis and transfer of low-defect monolayer graphene for field-effect transistors that will enable graphene nanoelectronics.
