Abstract
In this study, we investigated the electronic conductance of two typical single-wall nanotubes with square lattice by using Green’s function method in tight-binding approximation. Then the effect of various factors such as presence of symmetrical bond defects, the distance between two defects and the nanotube hopping energies was studied on the system electronic conductance. The square and rhombic nanotubes showed metallic and insulator/semiconductor behaviors, respectively.
