摘要：
The magnetopolaron is investigated in parabolic quantum wells in the presence of a tilted magnetic field. The Landau levels of polarons in GaAs/Ga1-xAlxAs parabolic quantum Hells are calculated for different subbands. The effect of the electron-phonon interaction on the polaron energy levels is inducted within second-order perturbation theory. The influence of the direction of the magnetic field on the polaron effect an the different electron energy levels is studied. Possible magnetopolaron resonances are also discussed.
