摘要

In this work, we extend analytically Green's function (GF) formalism to calculate the electrical conductance for an armchair SWCNT in the ballistic and linear response regime. We obtain an exact analytical formula for the conductance of the SWCNT, in the tight-binding (TB) approach and assuming nearest-neighbor interaction by recursion process in the GF formalism. We show that in the presence of homogeneous external potential, the number of conductance channels and resonance energy range of the system decrease.
