Edge Channel Dominated Magnetotransport in PbTe Wide Parabolic Quantum Wells
Abstract
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 as known from the quantum Hall effect. At the same time a non-local signal is observed which corresponds to the structure in Rxx and Rxy. We find a striking correspondence between a standard quantum Hall system and this quasi 3D WPQW system.
