Quantum transport and mobility spectrum of topological carriers in (001) SnTe/PbTe heterojunctions
D. Śnieżek, Jarosław Wróbel, M. Kojdecki +6
Measurements of magnetotransport in SnTe/PbTe heterojunctions grown by the MBE technique on (001) undoped CdTe substrates were performed. At low magnetic fields, quantum correction…
Macroscopic Quantum Tunneling of a Topological Ferromagnet
Kajetan M. Fijalkowski, Nan Liu, Pankaj Mandal +4
The recent advent of topological states of matter spawned many significant discoveries. The quantum anomalous Hall effect[1-3] is a prime example due to its potential for applicati…
Quantum anomalous Hall edge channels survive up to the Curie temperature
Kajetan M. Fijalkowski, Nan Liu, Pankaj Mandal +4
Achieving metrological precision of quantum anomalous Hall resistance quantization at zero magnetic field so far remains limited to temperatures of the order of 20 mK, while the Cu…
Any Axion Insulator Must be a Bulk Three-Dimensional Topological Insulator
K. M. Fijalkowski, N. Liu, M. Hartl +11
In recent attempts to observe axion electrodynamics, much effort has focused on trilayer heterostructures of magnetic topological insulators, and in particular on the examination o…
Femtosecond Transfer and Manipulation of Persistent Hot-Trion Coherence in a Single CdSe/ZnSe Quantum Dot
Philipp Henzler, Christian Traum, Matthias Holtkemper +8
Ultrafast transmission changes around the fundamental trion resonance are studied after exciting a p-shell exciton in a negatively charged II-VI quantum dot. The biexcitonic induce…
Coexistence of surface and bulk ferromagnetism mimics skyrmion Hall effect in a topological insulator
Kajetan M. Fijalkowski, Matthias Hartl, Martin Winnerlein +5
Here we report the investigation of the anomalous Hall effect in the magnetically doped topological insulator (V,Bi,Sb)2Te3. We find it contains two contributions of opposite sign.…
