【 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.
