In this work, the focus of the time-resolved experiments is on the modulationdoped single-well structures. These are of high-quality but have the disadvantage that they only exhibit weak Four Wave Mixing signals. Up to now, only results on the doped multiple well structures exist. A main part of the Four Wave Mixing experiments focuses on the two-dimensional electron gas at ...
