We examine the Fermi energy ϵ dependence of the conductance and show it is quantized into zero, one, and two times the conductance quantum e2/πh depending on the type of vacancy in the half-filled case, i.e., ϵ=0. In the presence of a magnetic field, the conductance is scaled by the component of the magnetic field in the direction of the vacancy 关键词: carbon nanotubes;electrical conductivity;Fermi level;tight-binding calculations;conductance;C nanotubes;vacancy;tight-binding model;Fermi energy;quantization;half-filled case;magnetic field;C
