Low-temperature thermopower in disordered carbon nanotubes

Abstract

Lowtemperature thermopower in disordered carbon nanotubes was calculated while taking into account multiple elastic electron scattering on impurities and shortrange structural inhomogeneities. A possible explanation is presented for the lowtemperature behavior of thermopower which depends on defect structure, impurities and chirality.
