Image of FIG. 1.
FIG. 1.

Photoluminescence spectrum of the modulation-doped QW with a high density 2DEG measured at in magnetic field . Characteristic energies are marked with arrows.

Image of FIG. 2.
FIG. 2.

Relative changes of the PL intensity from the QW with a high density 2DEG measured at at characteristic energies. Linear background has been subtracted and offset has been added for more clarity.

Image of FIG. 3.
FIG. 3.

A fast Fourier transform power spectrum of the relative changes of the PL intensity in magnetic field. Dashed line corresponds to the frequency of SdH oscillations. Offset is added for clarity.

Image of FIG. 4.
FIG. 4.

Dependence of the frequencies of the PL oscillations on the detection energy. Dashed lines correspond to theoretical dependences for three processes: the recombination of free electrons and free holes (f.f.); free electrons and bound holes (f.b.), and LO-phonon assisted recombination of free electrons and bound holes (LO-f.b.). Open circles correspond to frequencies measured at characteristic energies of the spectrum.
