摘要: Abstract In this paper, a Green's function study of transport through nano-wire in the presence electron–electron interaction and external electric field is presented. The total Hamiltonian above problem written tight binding approximation Hubbard term used to model between electrons central region. Our results show that interacting model, conduction gap will open. Also, if strong enough, negative differential resistance (NDR), which related localization charge, not occur.
