Temperature effects on crosstalk in carbon nanotube interconnects

In this paper, the authors propose two modified temperature-dependent equivalent circuit models for single- and double-walled carbon nanotube (SWCNT & DWCNT) interconnects at first, and the temperature effect on crosstalk in SWCNT and DWCNT interconnects are investigated, respectively. The crosstalk-induced delay and noise of these novel interconnects are characterized numerically over a temperature range from 300 to 600K. The simulation results show that the crosstalk-induced delay increases significantly and the noise increases slightly while the temperature is raised, which indicate that the performance and reliability degrade with an increase in CNT interconnects temperature.
