Electrostatic capacitance extraction for carbon nanotube interconnects

Carbon nanotubes are promising candidates for futuristic nanoelectronic applications due to their excellent properties. In this paper, we present a comprehensive modeling and calculation of electrostatic capacitances for various carbon nanotube systems that can be used to model interconnects in nanotechnology circuits. We provide results for single walled, multiwalled and bundles of single-walled carbon nanotubes as functions of the various design parameters. Numerical computations were performed using the method of moments in conjunction with a Greenpsilas function appropriate for the geometry of the interconnects.
