Abstract

The optical properties of the quasi-two-dimensional electron gas are investigated in the low density regime with special attention for the effects of a finite hole mass and bound excitonic states. A mean-field theory is employed which allows a consistent treatment of magnetic-field dependent screening in the integer quantum Hall regime. It is argued that higher-order scattering effects are difficult to identify by experiment. Recent luminescence experiments involving a higher subband can be explained as an equilibrium phenomenon in terms of an exciton unbinding transition proposed earlier.
