Theory of transport in carbon nanotubes

Abstract

A brief review is given of electronic and transport properties of carbon nanotubes mainly from a theoretical point of view. The topics include a giant Aharonov-Bohm effect on the bandgap and a Landau-level formation in magnetic fields, absence of backward scattering except for scatterers with a potential range smaller than the lattice constant, a conductance quantization in the presence of short-range and strong scatterers such as lattice vacancies and transport across junctions between nanotubes with different diameters.
