We review our optical experiments on two-dimensional electron systems (2DES) of different mobilities, realized in modulation-doped GaAs-AlGaAs single quantum wells, in quantizing magnetic fields. The carrier densities of the 2DESs could be tuned in a quite broad range between about 1 × 1010 cm-2 and 2 × 1011 cm-2 via gate electrodes. In photoluminescence (PL) and absorption experiments on 2DES ...
