Abstract
We studied the stationary electron transport of semiconduction single-wall straight and helically coiled carbon nanotubes in the presence of electron- phonon interaction. The electron and phonon bands as well as electron phonon coupling matrix elements are obtained from quantum mechanical calculations with the application of symmetry. Total scattering rate for all electronic states relevant for charge transport is obtained as a sum over independent processes. Transport simulation is realized by Monte Carlo algorithm, where free flight time and scattering mechanism are selected randomly. The obtained electron transport properties of helically coiled and straight carbon nanotubes are significantly different. The electron drift velocities in helically coiled nanotubes are several times lower than in straight carbon nanotubes.
