Abstract

CNTbands is a Matlab script that computes E(k) and the density-of-states (DOS) vs. energy for a carbon nanotube specified by (n, m). It uses a simple model that treats the nanotube as a rolled up graphene sheet whose band structure is computed by a simple tight binding approach and assumes a single pi orbital per carbon atom. In addition to plotting E(k) and DOS(E), the script also computes some basic parameters of the nanotube such as
diameter, number of hexagons in the unit cell, etc.
