Exploring Multi-layer Graphene Nanoribbon Interconnects

In this paper, an improvement of the existing conductance model for the single-layer GNR and a novel conductance model for multi-layer GNR are introduced. The models leverage the recent theoretical and theoretical results, providing consistent conductance/resistance estimations with the experimental results. Using these models, comparison of the resistance of multi-layer GNR with Cu and CNT bundle for the same aspect ratio is carried out. The results demonstrate that multi-layer GNR will be a superior interconnect solution over Cu for 45nm or less technology nodes. This work introduced a promising graphene interconnect by utilizing multiple layers. This might lead to future breakthrough of the new emerging interconnect solution.
