Abstract
AbstractElectron‐phonon and electron‐defect scattering rates have been calculated within a tight‐binding approach for semiconducting zigzag carbon nanotubes. The scattering rates for (5,0), (7,0), (10,0), (13,0) and (25,0) nanotubes have been investigated. The electron‐phonon scattering rate shows both diameter and temperature dependence, and the dependence of the electron‐defect scattering rate on nanotube diameter is similar to that of the electron‐phonon scattering rate. Backscattering and forward scattering for electrons interacting with defects occur with equal probability at all energies. The importance of electron‐defect scattering relative to electron‐phonon scattering depends very much on the energy of the electron (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
