Abstract :
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 5×1012 cm-2 at room temperature.
