Abstract: This paper analyzes the stability of carbon nanotube (CNT) and graphene nanoribbon (GNR) based interconnects for future VLSI technology node. We have analyzed both Bode and Nyquist stability of single-wall CNT, multi-wall CNT, GNR, and copper based interconnect systems. The stability analysis is performed for different interconnect systems for 16nm ITRS technology node. It is shown that densely packed single-wall CNT bundle based interconnect has highest gain margin for a wide range of interconnect length (1 m to 100 m) as compared to the other interconnect systems
Keywords: Carbon nanotube (CNT), graphene nanoribbon (GNR), stability.
