The cyclotron resonance (CR) spectra are calculated for a high electron density GaAs/AlAs quantum well in a tilted magnetic field. The CR peaks are split due to (i) the resonant magnetopolaron effect and (ii) the anticrossing of the CR mode and the plasmon-phonon intersubband modes. The derived CR peak positions and amplitudes are in good agreement with experiment. It is shown that the experimental CR spectra find an adequate explanation within Fröhlich's polaron concept. |
