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…
Spin injection and detection in all-van der Waals 2D devices
Jan Bärenfänger, Klaus Zollner, Lukas Cvitkovich +7
In this work we report efficient out-of-plane spin injection and detection in an all-van der Waals based heterostructure using only exfoliated 2D materials. We demonstrate spin inj…
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…
Measuring anisotropic spin relaxation in graphene
Sebastian Ringer, Stefan Hartl, Matthias Rosenauer +5
We compare different methods to measure the anisotropy of the spin-lifetime in graphene. In addition to out-of-plane rotation of the ferromagnetic electrodes and oblique spin prece…
