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…
