Highly crystalline superconducting TiN resonators grown on thermally reconstructed sapphire
Thomas J. Smart, Marc Neis, Janine Lorenz +15
High quality crystalline growth of a thin film on sapphire requires sufficient substrate preparation, often achieved via the use of aggressive chemical cleaning. Direct thermal rec…
Giant orbital Zeeman effects in a magnetic topological van der Waals interphase
Tobias Wichmann, Mirco Sastges, Keda Jin +10
Van der Waals (vdW) heterostructures allow the engineering of magnetic and electronic properties via interfacial orbital hybridisation and charge transfer. The resulting electric f…
Defect-induced displacement of topological surface state in quantum magnet MnBiTe
Felix Lüpke, Marek Kolmer, Hengxin Tan +6
The topological magnet MnBiTe (MBT), with gapped topological surface state, is an attractive platform for realizing quantum anomalous Hall and Axion insulator states. Howev…
Imaging the transition from diffusive to Landauer resistivity dipoles
Serhii Kovalchuk, David Kämpfer, Jonathan K. Hofmann +6
A point-like defect in a uniform current-carrying conductor induces a dipole in the electrochemical potential, which counteracts the original transport field. If the mean free path…
Shear-resistant topology in quasi one-dimensional van der Waals material BiBr
Jonathan K. Hofmann, Hoyeon Jeon, Saban M. Hus +10
BiBr is a prototypical quasi one-dimensional (1D) material in which covalently bonded bismuth bromide chains are arranged in parallel, side-by-side and layer-by-layer, with…
One-dimensional topological superconductivity in a van der Waals heterostructure
Jose Martinez-Castro, Tobias Wichmann, Keda Jin +8
One-dimensional (1D) topological superconductivity is a state of matter that is not found in nature. However, it can be realised, for example, by inducing superconductivity into th…
An unexplored MBE growth mode reveals new properties of superconducting NbN
John Wright, Celesta Chang, Dacen Waters +8
Accessing unexplored conditions in crystal growth often reveals remarkable surprises and new regimes of physical behavior. In this work, performing molecular beam epitaxy of the te…
Realizing gapped surface states in magnetic topological insulator MnBiSbTe
Wonhee Ko, Marek Kolmer, Jiaqiang Yan +7
The interplay between magnetism and non-trivial topology in magnetic topological insulators (MTI) is expected to give rise to a variety of exotic topological quantum phenomena, suc…
Investigation of unconventional reconstruction and electronic properties on the Na2IrO3 surface
F. Lupke, S. Manni, S. C. Erwin +3
Na2IrO3 is an intriguing material for which spin-orbit coupling plays a key role. Theoretical predictions, so far unverified, have been made that the surface of Na2IrO3 should exhi…
