Abstract :
Physics-based equivalent circuit models are presented for armchair and zigzag graphene nanoribbons (GNRs), and their conductances have been benchmarked against those of carbon nanotubes and copper wires. It is demonstrated that GNRs that have large coherence length behave like waveguides for electrons. This poses both challenges and opportunities for designing graphene nanoelectronic circuits.
