Abstract
Using a variational technique, the change of ground-state energy and binding energy of an impurity atom with impurity position and well width in a GaAs-As quantum well is calculated. In the calculation the electron–surface-optical-phonon interactions are taken into account. The result is discussed. It is found that the electron-phonon interaction energy depends not only on the width of the well but also on the position of the impurity atom in the well.
