Abstract
The backscattering contribution to the conductivity, irrelevant for metalli c single-walled carbon nanotubes, is proved to become more significant for doped semiconducting systems, in agreement with experiments. In the case of multiwalled nanotubes, the intershell coupling is further shown to enhance the contribution of backscattering for "metallic" double-walled, whereas i t remains insignificant for "metallic/semiconducting" double-walled systems .
