Impact of parameters variability on the electrical performance of carbon nanotube interconnects

This paper addresses the simulation of carbon nanotube interconnects with the inclusion of the effects of parameter uncertainties due to the fabrication process. The proposed approach is based on the available state-of-the-art models of nanointerconnects and on the expansion of the voltage and current variables in terms of orthogonal components, leading to an enhanced stochastic model. The method offers comparable accuracy and improved efficiency in computing parameters variability effects on system responses with respect to conventional methods like Monte Carlo. A realistic application example involving the frequency-domain analysis of an high-speed nanointerconnect concludes the paper.
