CNTphonons calculates the phonon band structure E(k) and the corresponding density of states DOS(E) for any arbitrary carbon nanotube. The calculation is based on the force constant method using parameters obtained for graphene proposed by Saito et al. This tool complements CNTbands, developed by J. Guo.
