Conductance modeling for graphene nanoribbon (GNR) interconnects

Graphene nanoribbons (GNRs), which are single graphene sheets, share many of the fascinating electronic, mechanical, and thermal properties of carbon nanotubes. Compact physical models for conductance of GNRs as functions of chirality, width, Fermi level, and the type of electron scatterings at the edges are presented. For widths below 8 nm, the models demonstrate that single-layer GNRs can potentially outperform copper wires with unity aspect ratio.
