| Abstract: | We study the electronic properties of a quantum system formed by two charged particles moving in a quantum wire (QW) with finite width σ and interacting through a Coulomb potential under an uniform electric field E applied over a spatially confined region of thickness 2a (-a<z<a). The number of electronic states of this finite width system is twice the number of the less realistic system with σ=0. |
