• 論文の詳細を見る

• We theoretically investigate electronic transport properties of a distorted carbon nanotube and estimate conductance shift for the sub-band conduction. In this simulation nanotubes are distorted in such a way that they make shapes of various vibrational modes. We find that the shift depends on the way of distortion. Thus, if the distortion is induced by selective excitation of a phonon mode by a monochrome light, we may expect clear response in the electronic current through the biased nanotube, which implies its possible application as a current switching device.
