摘要
Pressure induced hydrogenic donor impurity of ground and excited state in a GaAlAs/GaAs/GaAlAs corrugated quantum well is investigated. The calculations have been carried out using variational technique within the single band effective mass approximation taking into account the anisotropy and the corrections due to the conduction band nonparabolicity. The energy dependent effective mass and the position dependent quantity (Rashba spin-orbit splitting energy) are introduced to obtain the binding energy as a function of well width in the influence of pressure. The obtained results are compared with the other existing literature available. (C) 2010 Elsevier B.V. All rights reserved.
