Abstract

We investigate modulation-doped GaAs-AlGaAs quantum wells by photoluminescence spectroscopy. External gates allow us to tune the carrier densities below 1011 cm - 2, where we observe a crossover from an extended two-dimensional electron system to a regime where negatively charged excitons start to appear. By applying an external magnetic field, we can clearly resolve singlet and triplet excitons ...
