Abstract. A systematic investigation of the electronic transport properties of Haeckelite nanotubes using ab initio calculation is presented. The Haeckelite nanotube is coupled with Haeckelite nanotubes and bulk Au electrodes, respectively. Negative differential resistance and nonlinear conduction phenomena have been observed in the simulated I–V curves. Our results suggest that this behavior is attributable to the band mismatch between left and right electrodes, which implies that some intriguing electronic transport characteristics could be realized by using nanoscale electrodes.
