A RC model for multiwalled carbon nanotubes as interconnects

Abstract

In current researches, various equivalent circuit models have been demonstrated to study the performance of multiwall carbon nanotubes (MWCNTs). However, most of these models are very complex and predominately use SPICE/HSPICE simulations resulting in high computational time. This paper presents a compact RC model for MWCNT interconnects by different analysis of resistance in RC model. Using this approach, an efficient RC model for MWCNT bundle is also proposed here, for the first time. In this work, delay modeling of MWCNT interconnects is performed by using Elmore delay expression (EDE), that has shown good agreement with the reference model. The percentage error of the delay for both MWCNT and MWCNT bundle interconnects is found to be less than 2%.
