Ex Situ Fabrication of Superconducting Nanostructures for Low-Temperature STM
Adrian Greichgauer, Roozbeh Yazdanpanah, Alexey Taskin +3
Nanofabrication of topological insulator (TI) devices is essential for accessing edge and interface states, but conventional lithography and etching compromise the atomically clean…
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…
Non-Majorana-origin of the half-integer conductance quantization elucidated by multi-terminal superconductor-quantum anomalous Hall insulator heterostructure
Anjana Uday, Gertjan Lippertz, Bibek Bhujel +2
Chiral one-dimensional transport can be realized in thin films of a surface-insulating ferromagnetic topological insulator called quantum anomalous Hall insulator (QAHI). When supe…
