| Zusammenfassung | A coupled multi-quantum well GaAs/AlGaAs heterostructure has been doped in such a way that the widest quantum well is composed of a conductive layer of a two-dimensional electron gas whereas the narrower quantum wells are free of mobile charge carriers at low temperatures. Photoluminescence measurements exhibit a broad signal of the coupled quantum wells and a surface acoustic wave has been used to excite the electronic system. |
