Carbon nanotubes (CNTs) have emerged as a potential nanoelectronic material that can replace traditional copper as the material for very large scale integrated circuits (VLSI) interconnects.In this article, we have quantified the performance expected out of CNTs-based interconnect systems based on realistic characterization of their Tomonaga Luttinger theory-based transmission line model. We have presented performance estimates for bus systems consisted of single-walled nanotubes and crystalline bundles of CNTs. Results indicate that the bundles offer at leasta 10 times performance advantage over isolated nanotubes. However, this is at the expense of larger signal damping associated with them.
