Hydrogenation of Graphene Nanoribbon Edges: Improvement in Carrier Transport.

This letter is the first to present a method to selectively hydrogenate the edges of sub-30-nm graphene nanoribbons (GNRs). After hydrogenation of the edges, the GNRs exhibit improved transport properties; carrier mobility increases by up to 50% at a carrier density of 5\times 10^12~cm^-2 at room temperature.
