✦ Synopsis


A brief review is given on electronic and transport properties of carbon nanotubes mainly from a theoretical point of view. The topics also include a description of electronic states in a tight-binding model and in an effective-mass or kβ€’p scheme. Transport properties are discussed including absence of backward scattering except for scatterers with a potential range smaller than the lattice constant, its extension to multi-bands cases, long-wavelength phonons and electron -phonon scattering, effects of lattice vacancies, and junctions together with topological defects.

Transport measurements on a bundle of single-walled carbon nanotubes have been made below 4.2 K as a function of side gate and source-drain bias voltage. The transport of an individual nanotube is described by the Coulomb blockade effect. The zero-dimensional quantum states of the nanotube become cl
