Copper-based interconnects are widely employed in integrated circuits in a variety of semiconductor technologies and applications but they are fast reaching their limits. This is because their resistivity increases and current-carrying capacity decreases as they are made smaller. A team of researchers at the University of California at Santa Barbara has now shown that intercalation-doped multilayer graphene nanoribbons (ML-GNRs) could make good alternatives to copper in this context because they are better in terms of performance, reliability and energy efficiency down to 20 nm width. Preliminary measurements also show that their properties could improve even further as they are made narrower than 20 nm………
