Green’s function theory of electrical and thermal transport in single-wall carbon nanotubes

The temperature dependencies of electrical conductivity and thermopower are studied for single-wall carbon nanotubes using a Green’s-function theory developed to incorporate band structure, dielectric function, and electron-phonon interaction effects. Armchair and zigzag tubes are considered. They exhibit quite different temperature dependencies of the transport coefficients. Some experimental results are compared with the present calculations.
