Abstract
By applying non-equilibrium Green's function formalism combined with first-principles density functional theory, we have investigated the electronic transport properties of a carbon nanotube-based molecular junction with different terminations (H-, C- and N-). The results show that the different terminations at the carbon nanotube ends strongly affect the transport properties of the junction. The current through the N-terminated carbon nanotube junction is significant larger than that through the H- and C-terminated junctions at low biases. Moreover, negative differential resistance behaviors can be observed in the N-terminated carbon nanotube junction, whereas not in the other two cases.
