Analysis of Stability in Carbon Nanotube and Graphene Nanoribbon Interconnects

This paper analyzes the stability of carbon nanotube(CNT) and graphene nanoribbon (GNR) based interconnects forfuture VLSI technology node. We have analyzed both Bode andNyquist stability of single-wall CNT, multi-wall CNT, GNR, andcopper based interconnect systems. The stability analysis isperformed for different interconnect systems for 16nm ITRStechnology node. It is shown that densely packed single-wall CNTbundle based interconnect has highest gain margin for a widerange of interconnect length (1 m to 100 m) as compared to theother interconnect systems.
