The Binding Energy of Impurities in the Asymmetrical Semi-Exponential Quantum Wells
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 4
Abstract
Within the framework of effective-mass and envelope wave function approach, using a variational method, we have investigated the binding energy of shallow-donor impurities in an asymmetrical semi-exponential quantum wells (ASEQW). The obtained numerical results show that the structure parameters (σ and, V0) lead to significant changes in the impurity binding energy. Furthermore, these results show that the hydrogenic donor impurity binding energy may be increased or decreased as a function of the impurity position in quantum well.
