Electronic transport through a ladder nanostructure in the presence of network defects
2012
Iranian Journal of Physics Research
The present research studied the electronic transport of an ideal infinite ladder nanostructure in the presence/absence of network defects by using Green's function method at the tight-binding approximation. The network defects can be simulated by considering a finite ladder which is connected via two contacts to two similar infinite ladders. The results showed that the hopping energy of rungs determines the overlapping region of the ladder conductance channels. By increasing hopping energy of
