Phasecoherent Transport in PbTe Wide Parabolic Quantum Wells
J. Oswald, G. Span, A. Homer +4
Conductance fluctuations have been observed in macroscopic, quasi 3D PbTe wide quantum wells. A significant increase of the correlation field occurs in a temperature range from 40…
Edge Channel Dominated Magnetotransport in PbTe Wide Parabolic Quantum Wells
J. Oswald, G. Span, A. Homer +4
In PbTe wide parabolic quantum wells (WPQW) a plateau-like structure is observed in the Hall resistance, which corresponds to the Shubnikov-de Haas oscillations in the same manner…
Anomalous magnetotransport in wide quantum wells
J. Oswald, G. Span, A. Homer +4
We present magneto transport experiments of quasi 3D PbTe wide quantum wells. A plateau-like structure in the Hall resistance is observed, which corresponds to the Shubnikov de Haa…
Non Local Transport in PbTe Wide Parabolic Quantum Wells
J. Oswald, G. Heigl, G. Span +4
The results of non-local experiments in different contact configurations are discussed in terms of a non-local behaviour of the contact arms. It is shown that the observed reproduc…
Quenching of the Quantum Hall Effect in PbTe Wide Parabolic Quantum Wells
J. Oswald, G. Heigl, G. Span +4
We show that for the case of a many valley host semiconductor an edge channel (EC) related non-local behaviour can persist also in the 3D-regime where the quantum Hall effect (QHE)…
Conductance Fluctuations in PbTe Wide Parabolic Quantum Wells
J. Oswald, G. Heigl, G. Span +4
We report on conductance fluctuations which are observed in local and non-local magnetotransport experiments. Although the Hall bar samples are of macroscopic size, the amplitude o…
