Zusammenfassung: | Single-photon superradiance was studied at cyclotron resonance in an ideal single-crystal semiconductor p-type film, with a cubic structure placed in a homogeneous static strong magnetic field perpendicular to the film surface. The analysis was performed at a low temperature, at which the density of holes at the Landau level n = 0 was maximum, and at the Landau level n = 1 was zero. The current density in the film was calculated using the Lindblad equation for the density matrix, and the parameters of electromagnetic field radiated by the film in the saturation mode, when the radiated electric field strength was high, were studied. It was shown that the universal loss power per unit area of the film depends only on the fundamental constants c, qe, and me, and on the induction of the magnetic field. The conductivity of the film was calculated. |
