RF Performance Analysis of Graphene Nanoribbon Interconnect

The work in this paper presents analysis of graphene nanoribbon (GNR) as nano-interconnect for radio-frequency (RF) VLSI circuits for 16 nm technology node. A frequency dependent electrical equivalent model is developed by calculating the circuit parameters based on interconnect geometry. Using the developed model the RF performance of GNR based interconnects is investigated and compared to that of copper based interconnects for 16 nm technology node. It is shown that GNR based interconnect shows better performance for operating in and beyond 1000 THz frequency range for shorter interconnect length.
