Abstract
We solve the Green's equation exactly for the armchair-type carbon nanotube s with one pi-electron tight-binding Hamiltonian and obtain analytic expres sions for the conductance of the nanotube with local perturbations. Our res ults explicitly show the dependence of the conductance on the Fermi level, the tubular radius, and the strength of the perturbation. (C) 1999 Elsevier Science Ltd. All rights reserved.
