▎ 摘　　要

This paper establishes the importance of the lithium (Li) intercalation in multilayer graphene nanoribbon (MLGNR) interconnects for obtaining superior performance than conventional copper (Cu) on-chip interconnects. For the first time, we report performance analysis of Li-intercalated MLGNRs for local interconnect applications. In that, interconnect thickness is optimized for obtaining lowest delay and energy-delay-product (EDP). At 12 mu m interconnect length, our optimized Li-intercalated MLGNRs exhibit (approximate to 22.9 ps) 1.9x and 4.1x lower delay and EDP, respectively, when compared to Cu. Even in presence of edge roughness, they exhibit (approximate to 31.8 ps) 1.37x and 2.5x lower delay and EDP, respectively, when compared to Cu. Our analysis quantitatively proves the potential of Li-intercalated MLGNRs for local interconnect applications.
