Abstract (English)

Within the framework of this PhD we report on the very first observation of the fractional Quantum Hall Effect (FQHE) in both, a non-magnetic CdTe and a semimagnetic Cd1-xMnxTe quantum well device. To our knowledge, this constitutes the first demonstration of this effect in the II-VI material family. Furthermore, our results reveal that the formation of fractional Quantum Hall states is not ...

Im Rahmen dieser Dissertation berichten wir über die allererste Beobachtung des fraktionalen Quanten Hall Effekts (FQHE), sowohl in nicht-magnetischen CdTe, als auch in semimagnetischen Cd1-xMnxTe Quanten Wells. Nach unserem Kenntnisstand stellt dies den ersten Nachweis dieses Effektes in der II-VI Materialfamilie dar. Darüber hinaus zeigen unsere Resultate, daß das Auftreten von fraktionalen ...
