Abstract

The conductance of carbon nanotubes with a Stone-Wales defects composed of two pentagon-heptagon pairs is calculated in an effective-mass approximation. The presence of topological defects is represented as a nonlocal potential. The results obtained in the k · p scheme agree with those in a tight-binding model.
