Observation of the surface hybridization gap in the electrical transport properties of the ultrathin topological insulator (BiSb)Te
Feike van Veen, Sofie Kölling, Stijn R. de Wit +4
We study the three-dimensional topological insulator (BiSb)Te in its ultrathin limit i.e. when the thickness is of the same order as the surface state pen…

Dynamics of current-induced switching in the quantum anomalous Hall effect
Alina Rupp, Daniel Rosenbach, Torsten Röper +4
Ferromagnetic topological insulators in the quantum anomalous Hall (QAH) regime host chiral, dissipationless edge states whose propagation direction is determined by the internal m…

Breakdown of the quantum anomalous Hall effect under microwave drives
Torsten Röper, Daniel Rosenbach, Achim Rosch +3
Quantum anomalous Hall (QAH) insulators exhibit chiral dissipationless edge states without an external magnetic field, making them a promising material for quantum metrology and mi…
