In this work, the phonon-assisted cyclotron resonance in a special symmetric quantum well is studied in detail by evaluating the magneto-optical absorption coefficient (MOAC) and the full width at half maximum (FWHM). The results include the two-photon absorption process and the electron–phonon interaction as well. The influence of the magnetic field, the quantum well parameter, and the temperature on the MOAC and the FWHM is illustrated plainly. Our results are in good agreement with those accessible to the theoretical and experimental works of literature. In addition, we found a new rule of the temperature-dependent FWHM for the phonon absorption process, which should be examined by an experiment work in the future.
