A generalized model for the signal propagation along single- and multi-walled carbon nanotubes with arbitrary chirality

The paper presents a self-consistent semi-classical model describing the electrical behavior of carbon nanotube interconnects. The model deals with the general case of arbitrary chirality and takes rigorously into account the effects of nanotube size and chirality on its electrical parameters. The general model includes as particular cases the models currently used in literature to describe metallic carbon nanotubes with small radius. The analysis of bundles of single-walled and multi-walled carbon nanotubes is carried-out. The model is also used to derive a semi-analytical approximation for the number of equivalent conduction channels in a multi-walled carbon nanotube shell.
