Energy levels of an impurity atom and its binding energy in a quantum dot with electron–phonon interactions are obtained by the second-order Rayleigh–Schrodinger perturbation theory. The energy correction is expressed as a function of the temperature, the applied magnetic field, and the effective confinement length of the quantum dot. We apply our calculations to GaAs .

The hamiltonian operator corresponding to a GaAs parabolic quantum dot is formulated by analyzing carefully the terms of this operator. In this formulation, certain plasma aspects are discussed with respect to the hamiltonian. Our study is referred to the absence of electric and magnetic fields.

The Fermi energy level, that is, the chemical potential associated with an excitonic gas in a semiconductor within a non-parabolic quantum dot is calculated by determining previously the corresponding Fermi velocity of excitons conceived as confined in a spherical quantum box on the basis of the energy levels of the hydrogen atom. From the Fermi energy calculation, the reduced effective mass of an electron–hole pair is found to be dependent upon the spatial exciton density. In addition, some aspects related to quantization of the Fermi energy in question and temperature dependence are discussed.
