An analytical model for Normalised Conductances and Resistances of Borophene on-chip Interconnect

In this work, we focus on enhancing performance at the most advanced technology nodes by addressing key challenges like conductances and resistances in traditional VLSI on-chip copper interconnects. To achieve this, we introduce a novel interconnect material: borophene. Borophene, a crystalline form consisting of a monolayer of boron atoms, was theoretically predicted in the mid-1990s and was first synthesized experimentally in 2015. We present equivalent circuit models for interconnects using Borophene Nanoribbons (BNRs), examining both armchair and zigzag configurations. The conductance and resistance of these BNR configurations are benchmarked against those of armchair and zigzag graphene, as well as conventional copper wires. The normalized conductance of borophene and graphene is also analyzed. Our findings reveal that the conductance and normalized conductance of borophene with smooth edges are comparable to graphene, offering greater strength and flexibility, while significantly outperforming copper. The use of borophene in interconnects demonstrates substantial improvements in performance by considerably reducing resistance compared to graphene
