• Resumen

  • Recent advances in the fabrication technology of heterojunction semiconductor nanostructures have made possible the realization of systems with extremely small sizes. In these devices, electrons are confined along some directions and are free to move in others. Semiconductor nanostructures have become so small that we have to take into account quantum effects. The two dimensional physical model consists of Poisson’s equation for the electrostatic potential φ, coupled with an eigenvalue problem for Schrödinger’s equation. Proposes.
