Electrostatic capacitances for carbon nanotube interconnects

Carbon nanotubes are promising candidates for futuristic nanoelectronic applications. In this article, we present a comprehensive modeling and calculation of electrostatic capacitances for various metallic carbon nanotube systems that can be used to model interconnects in nanotechnology circuits. Capacitance results are provided 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 Green\u27s function appropriate for the geometry of these interconnects
