Abstract
Magnetospectroscopic studies of a modulation-doped GaAs/InGaAs/GaAlAs quantum well (QW) are presented. Oscillations of the photoluminescence (PL) intensity in magnetic field are investigated. Recombination processes giving rise to the PL are identified and their effect on the PL is established. It is shown how measurements of the oscillations can provide information on the density of the quasi-two-dimensional electron gas confined in the QW.(c) 2006 American Institute of Physics.
