Abstract
Transport properties of disordered carbon nanotubes are investigated including long-range Coulomb interaction. The resistivity and optical conductivity are calculated by using the memory functional method. In addition, the effect of localization is taken into account by use of the renormalization-group analysis, and it is shown that the backward scattering of the intravalley and that of the intervalley cannot coexist in the localized regime. Differences between the transport properties for the metallic state with two valleys and those with one valley are discussed.
