FIG. 1.

(Color online) Effect of the electrostrictive deformation on the HOMO and LUMO energy levels and the gaps between them. (a) The energy levels of the CNT and (b) the corresponding energy gaps; (c) the energy gaps of the (5,0)/40 CNT ]; (d) the energy gaps of the CNT; with and without consideration of the electrostrictive deformation.

FIG. 2.

(Color online) The contour plots of HOMO and LUMO charge densities [in units of ] for the electron structures of different CNTs. The numbers 1, 2, and 3 denote the released, rigid, and electrostrictively deformed states under external electric fields, respectively. The electric fields applied here are (a) for the tube, (b) for the (5,0)/40 tube, (c) for the tube, and (d) for the capped (5,5) tube, respectively.

(Color online) Dipole moment of the armchair CNTs caused by external applied electric fields.
