Milliwatt terahertz harmonic generation from topological insulator metamaterials
Klaas-Jan Tielrooij, Alessandro Principi, David Saleta Reig +16
Achieving efficient, high-power harmonic generation in the terahertz spectral domain has technological applications, for example in sixth generation (6G) communication networks. Ma…
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…
Antiferromagnetic order in MnBi2Te4 films grown on Si(111) by molecular beam epitaxy
N. Liu, S. Schreyeck, K. M. Fijalkowski +4
MnBi2Te4 has recently been predicted and shown to be a magnetic topological insulator with intrinsic antiferromagnetic order. However, it remains a challenge to grow stoichiometric…
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…
