Abstract
The energy spectrum of a quasi-two-dimensional gas of non-interacting electrons in a homogeneous magnetic field fitted with respect to the confinement plane can be calculated exactly for the case of a parabolic quantum well potential. The authors investigate the influence of weak coupling polaron effects due to the Frohlich interaction with longitudinal optical phonon modes on this system for arbitrary magnetic field strengths and tilt angles. Magneto-polaron binding energies and optical transition energies are determined within second-order perturbation theory. Numerical results are presented for GaAs/AlGaAs-based structures.
