Spatial homogeneity of superconducting order parameter in NbN films grown by atomic layer deposition
J. Lorenz, S. Linzen, M. Ziegler +5
Due to their high kinetic inductance, highly disordered superconducting thin films are a potential hardware for the realization of compact, low-noise elements in cryoelectronic app…
Distributed Current Injection into a One-Dimensional Ballistic Edge Channel
Kristof Moors, Christian Wagner, Helmut Soltner +3
We generalize Landauer's theory of ballistic transport in a one-dimensional (1D) conductor to situations where charge carrier injection and extraction are not any more confined to…
Scattering makes a difference in circular dichroic angle-resolved photoemission
Honey Boban, Mohammed Qahosh, Xiao Hou +16
Recent years have witnessed a steady progress towards blending 2D quantum materials into technology, with future applications often rooted in the electronic structure. Since crossi…
Strong and Weak Three-Dimensional Topological Insulators Probed by Surface Science Methods
Markus Morgenstern, Christian Pauly, Jens Kellner +12
We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular…
Proximity-induced superconducting gap in the quantum spin Hall edge state of monolayer WTe
Felix Lüpke, Dacen Waters, Sergio C. de la Barrera +5
The quantum spin Hall (QSH) state was recently demonstrated in monolayers of the transition metal dichalcogenide 1T'-WTe and is characterized by a band gap in the two-dimension…
