An improved formalism for the Crank‐Nicolson finite‐difference time‐domain by conformal mapping method

Abstract

for different nanotube systems for the transmission line model. The algorithm used to perform the computations employed the method of moments in conjunction with a Green's function appropriate for the geometry of the interconnects. To reduce the number of discretization points, rectangular subsections and image charges were used. Our results suggest that when compared to standard metal interconnects, single walled nanotubes show a superior capacitance performance which would result in lower interconnect delays. Further, we have observed that MWNTs shield their inner shells very efficiently. Our studies of coupling capacitances for SWNT bundles suggest that adding an extra layer to the bundle results in a significant increase in the overall capacitances.
