Electrodynamics of Multiwall Carbon Nanotubes

Carbon nanotubes can be used as possible alternative to metals, like copper and aluminum, in nanoelecronics. In particular, bundles of either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) have been proposed to make interconnects and nanoantennas. The typical diameter of SWCNTs is roughly one nanometer and, depending on its chirality’s, can be either metallic or semiconductor. On the other hand MWCNTs have diameters in a wide range of a few to hundreds of nanometers and are composed of both metallic and semiconducting shells.
