Abstract
We have investigated the magneto-optical properties of GaAs1-xPx/Ga1-yAlyAs quantum wells (QW's) as a function of biaxial strain using photoluminescence excitation spectroscopy. The fan diagrams of the electronic transitions, for fields applied in the Faraday configuration, are analyzed in terms of two-dimensional exciton, using an hydrogenic model. We extract from the analysis the excitonic binding energies and their reduced effective masses. The polarization of the heavy- and light-hole excitons are compared with a theory of the spin relaxation of the photocreated carriers.
