Influence of tube diameter on carbon nanotube interconnect delay and power output

Abstract

AbstractThis paper address the influence of tube diameter on single walled carbon nanotube (CNT) bundle interconnect delay and power output in Very Large Scale application. We find that single‐walled carbon nanotube (SWCNT) bundle interconnects are of lower delay than copper interconnect due to low resistance and inductance. Power dissipation decreases with increase in tube diameter of the constituent SWCNT. CNT interconnect resistance and inductance increases with increase in tube diameter. On the other hand, with increase in tube diameter interconnect capacitance decreases. There is a trade off between delay and power dependence on tube diameter.
