TEMPERATURE EFFECT ON IMPURITY-BOUND POLARONIC ENERGY LEVELS IN A PARABOLIC QUANTUM DOT IN MAGNETIC FIELDS

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.
