Abstract

A multilayer graphene nanoribbon (GNR) less than 20 nm wide was synthesized by overlayer growth of graphene on a GNR template. First, very narrow template GNRs with widths of approximately 10 nm were prepared by unzipping from double-walled carbon nanotubes. Additional 4-5 layers of graphene were then formed on the pristine GNR template by chemical vapor deposition. Raman spectroscopy revealed that the synthesized multilayer GNR had turbostratic stacking without any structural correlation between the graphene layers. A large on/off ratio and a high on-current were observed in field effect transistors fabricated using the synthesized multilayer GNR channel.
