Conductance through the disclination dipole defect in metallic carbon nanotubes
arXiv:0912.5466 · doi:10.1088/1742-6596/248/1/012009
Abstract
The electronic transport properties of a metallic carbon nanotube with the five-seven disclination pair characterized by a lattice distortion vector are investigated. The influence of the disclination dipole includes induced curvature and mixing of two sublattices. Both these factors are taken into account via a self-consistent perturbation approach. The conductance and the Fano factor are calculated within the transfer-matrix technique. PACS: 73.63.Fg, 72.80.Rj, 72.10.Fk
