Magnetic field-bias current interplay in HgTe-based three-terminal Josephson junctions
J. Thieme, W. Himmler, F. Dominguez +8
We investigate HgTe/Nb-based three-terminal Josephson junctions in T-shaped and X-shaped geometries and their critical current contours (CCCs). By decomposing the CCCs into the con…

Quantum Hall effect and current distribution in the 3D topological insulator HgTe
S. Hartl, L. Freund, M. Kühn +8
We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain. Des…

Anomalous conductance steps in three-dimensional topological insulator HgTe-based quantum point contacts
Elisabeth Richter, Michael Barth, Dmitriy A. Kozlov +8
We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field , there is no quantizatio…
