Comparison of propagation delay in single- and multi-layer graphene nanoribbon interconnects

Abstract

Multi-layer graphene nanoribbons (MLGNRs) have potentially provided attractive solution over single-layer GNR (SLGNR) interconnects. This research paper presents an equivalent RLC model for GNR interconnects to study the effect of propagation delay. A driver-interconnect-load (DIL) system employing CMOS driver is used to analyze the performance. It has been observed that the overall delay performance is improved by 94.5% for MLGNR as compared to SLGNR.
