Self-Consistent and Full-Wave Analysis of Carbon-Nanotube Matrices for Multi-Channel Charge Confinement

This paper reports a theoretical characterization of carbon nanotubes matrices using a full-wave undulatory description of charge carriers, self-consistent with external and self-generated potentials. The effect of nanotubes coupling on charge and current confinement is described, by a new in-house simulation toolkit that can easily solve for 3D arrays of packed nanotubes, possibly multi-wall, in a multi-band framework. The availability of such a tool could be of crucial importance in view of the multiplicity of nanotechnology applications of CNT arrays as sensors, field effect transitors, quantum dots, interconnects and antennas.
