“…These materials show a strong electron-phonon coupling leading to significative modifications in the donor spectra due to the polaronic effects. As pointed out by several authors, [15][16][17][18][19][20][21][22][23][24] , the polaronic effects are more complicated in low dimensional semiconductors than in bulk ones due to the occurrence of interface and confined modes. Several theoretical studies have been devoted to the electron and donor optical-phonon coupling in QNC's but they were restricted to an infinitely deep potential model.…”

We have studied the simultaneous effects of magnetic and electric fields on the ground-state energy of a donor impurity confined in a polar CdSe quantum nanocrystallite embedded in a nonpolar matrix. Calculations are performed in the framework of the effective-mass approximation using the Hassé variational approach. We describe the effect of the quantum confinement by a finite deep potential and we take onto account the interaction between the charge carriers ͑electron and ion͒ and the confined longitudinal optical phonons ͑LO phonons͒. It is found that the corrections due to the LO phonons on the binding energy, the diamagnetic coefficient, and the polarizability are very important and cannot be neglected or ignored.

“…Several theoretical studies have been devoted to the electron and donor optical phonon coupling in SQDs but they were restricted to an infinitely deep potential model. Marini et al [17,18] have determined the Huang-Rhys factor in the model of a donor-like exciton located at the center of a CuCl SQD. Fedorov and Baranov [25] have studied the effect of longitudinal optical phonons (LOphonons) and SO phonons on the donor energy.…”

The effects of low electric field and finite-barrier height on the ground state energy of a donor impurity confined in a polar CdSe spherical quantum dot embedded in a non-polar matrix were studied. Calculations were carried out in the framework of the effective mass approximation using the Hassé variational approach. The effect of the quantum confinement was described by a finite deep potential taking into account the interactions between the charge carriers (electron and ion) and the confined longitudinal optical phonons (LO-phonons). It was found that the binding energy and the polarizability depend strongly on LO-phonon effects. So, the phonon corrections should not be ignored or neglected whatever the dot size and the degree of confinement.
