Low-temperature resistance of individual single-walled carbon nanotubes: A theoretical estimation

Abstract

The resistances of individual single-walled carbon nanotubes (SWNTs) are calculated based on Boltzmann transport equation, graphene approximation relation of electronic energy for SWNTs and weak localization (WL) theory. The theoretical results of resistance for SWNTs are compared with experimental measurements. It has been found that, for nearly metallic and semiconducting SWNTs the theoretical result is consistent with experimental data roughly, whereas for truly metallic SWNTs (armchair ones) the theoretical result is in good agreement with measurement.
