| Abstract: | The luminescence spectra due to recombination of two-dimensional electrons with optically excited holes have been studied
in a wide range of electron filling factors in the transverse magnetic field. A nonmonotonic filling-factor dependence of
the energy splitting between different circular polarizations of photoluminescence from the completely filled zeroth Landau
level of electrons has been observed. It has been shown that this dependence is associated with collective (excitonic) effects
that appear due to the interaction between electrons from partially occupied upper Landau levels and holes remaining on the
zeroth Landau level after recombination. |
