A theoretical study was made of quantum transport in carbon nanotubes in the presence of two different sources of scattering: a static short-range random potential that simulated lattice defects, superposed on a long-range time-dependent perturbation that mimicked phonon-induced real-space atomic displacements. In the weak-localization regime, fluctuations of the coherent length-scales were shown to be driven by band-structure features, whereas the phonon-induced delocalization effect occurred in the stronger-localization regime.
