THE CYCLOTRON-RESONANCE OF A 3-DIMENSIONAL IMPURITY MAGNETOPOLARON INTHE PRESENCE OF A STRONG PARABOLIC POTENTIAL

In this investigation, we study the combined effects of a parabolic po tential and a Coulomb impurity on the cyclotron resonance of a three-d imensional bound magnetopolaron, under the condition of strong parabol ic potential. We only consider the case of weak electron-LO-phonon cou pling and apply Larsen's perturbation method to the calculation of ene rgy levels. The polaron resonances in a low-lying energy level am stud ied and certain cyclotron effective masses are calculated. We apply ou r calculations to GaAs.
