Chirality Effects on an Electron Transport in Single-walled Carbon Nanotube Coupling to a Quantum Dot

摘要

We investigated the effects of asymmetric velocities of Dirac particles,calculated by inducing curvature-induced σ-π mixing and Slater-Koster type projection for π-π and σ-π hopping integrals,on the transfer energy between the quantum dot(QD)and electron in a carbon nanotube.We also showed that probability for finding the electron on the left-side is more than the right-side of carbon nanotube.This result corresponds with the asymmetric velocities of Dirac particles,such a study may prove a useful for charge transport of QD-solar cell.
