Analytical Time-Domain Models for Performance Optimization of Multilayer GNR Interconnects

In this paper, we are proposing novel analytical time domain models for side contact and top contact multilayer graphene nanoribbon (MLGNR) interconnects. Our proposed models give physical insights about the transient behavior of these MLGNRs. The proposed models have been verified with existing data as well as exhaustive simulation and exhibit excellent accuracy. Based on our analysis, we identify limiting factors that need to be considered for the design of optimum top contact MLGNRs that exceed the performance of copper and match that of side contact MLGNR interconnects. Finally, we compare the performance of our optimum top contact MLGNRs with optical interconnects to predict the future roadmap for next generation interconnect technology.
