Modeling and performance analysis of folded graphene nanoribbon interconnect

Abstract

In this paper, we have modeled the folded graphene nanoribbon (FGNR) interconnect and analyzed the performance for nanometer technology nodes. The mean free path is modeled as a function of GNR width and Fermi energy. The RLC equivalent circuit is modeled further for analyzing delay and RF response. The performance of FGNR is compared to that of multi‐layer horizontal graphene nanoribbon (ML‐HGNR) and multi‐layer vertical graphene nanoribbon (ML‐VGNR) interconnects. Our analysis shows that proposed FGNR interconnect with fully diffusive edges can outperform both the ML‐HGNR and ML‐VGNR interconnects as well as the traditional Cu interconnects.

Analysis of Power Supply Voltage Drop (IR-Drop) and Propagation Delay Using Folded Graphene Nano Ribbon Interconnect (F-GNR) Interconnect

“…The numerical F-GNR interconnect model was first proposed by D. Das et.al. reported in [18][19]. Although numerous researchers have studied GNR for interconnect applications, folded GNR (F-GNR) has never been studied for IR-Drop and propagation delay analysis for nano-electronic circuit applications.…”
