Modeling and performance analysis of multilayer zigzag graphene nanoribbon (zz-MLGNR) interconnect for VLSI application

Equivalent circuit model along with simple analytical formulas for calculating different circuit parameters of zigzag multilayer graphene nanoribbons (zz-MLGNR) has been proposed. The results obtained from proposed model are verified against existing models and an error of less than 5% is observed. The variation of equivalent circuit parameters with respect to temperature is analyzed. GNR interconnect time delay at 10 nm and 8 nm technology node is calculated using proposed model. It is observed that, the equivalent circuit parameters of zz-MLGNR is insensitive to temperature variation and doped multilayer GNR can potentially outperform copper in lower technology nodes.
