Abstract :
We report the results of polarized magneto-photoluminescence (MPL) measurements on a high mobility modulation-doped GaAs/AlGaAs single quantum well. The magnetic field was varied between 0 and 60 T. The appearance of a doublet structure in the heavy-hole magneto-exciton in the high field regime was interpreted as an indication for enhanced electron–hole exchange interaction induced by the confinement. The effective g-factor of the electron determined from the Zeeman splitting was 3.7 times higher than the bulk value.
