Cyclotron-resonance (CR) spectra of a gas of interacting polarons confined in a GaAs/AlAs quantum well are theoretically investigated taking into account the magnetoplasmon-phonon mixing and band nonparabolicity. Contributions of different magnetoplasmon-phonon modes to the total magnetopolaron coupling strength are investigated as a function of the electron density. It is confirmed theoretically, that the resonant magnetopolaron coupling in a high-density GaAs/AlAs quantum well occurs near the GaAs TO-phonon frequency rather than near the GaAs LO-phonon frequency. Calculated CR spectra are in agreement with recent experimental data. |
