Abstract

In this letter, novel Cu-graphene heterogeneous interconnects are studied by virtue of the equivalent circuit model. The effective resistances of such interconnects are extracted numerically, with the Cu/graphene and graphene/ graphene interface resistances treated appropriately. It is shown that such interconnects can provide superior performance and reliability over Cu wires for an on-chip interconnect applications.
