A Novel GNR Interconnect Model to Reduce Crosstalk Delay

In this research article, we have proposed a reduced thickness graphene nanoribbon (GNR) interconnect model to reduce crosstalk effects. The 10× higher current capability of GNR than copper (Cu) makes it an attractive choice to alleviate electro migration problem. The lower resistance of GNR is also an important factor to reduce interconnect delay. We have shown that the thickness of GNR interconnect can be reduced to reduce the crosstalk effects significantly without compromising the other benefits. Our analysis shows that the reduced thickness GNR interconnect can achieve ~2-3× reduction in crosstalk induced delay compared with Cu interconnects.
