摘要

Electronic properties of finite double-walled carbon nanotubes are calculated in the tight-binding model. Energy levels, energy gap, and the density of states strongly depend on the symmetry configurations, the nanotube length, and the transverse electric field. The intertube interactions change the level spacing, modify the energy gap, and destroy state symmetry about the Fermi level. The transverse electric field induces state crossing, destruction of state degeneracy, increase of low-energy states, and strong modulation of energy gap.
