Description
The effect of a magnetic field on the ground-state energy of a donor impurity confined in a polar CdSe spherical quantum dot embedded in a nonpolar matrix is studied theoretically. The interaction between the all charge carriers (electron and ion) and the confined longitudinal optical phonons (LO-phonons) is taken into account by considering the strong coupling method (Landau-Pekar approach). A variational calculation is performed in the framework of the effective mass approximation using a trial wave function deduced from the second-order perturbation and assuming that the quantum dot has a finite depth potential. © 2004 Elsevier B.V.
