A miniature evaporator for in-operando deposition of isolated atoms in a low-temperature scanning tunneling microscope
Jeongmin Oh, Hermann Osterhage, Vasily Cherepanov +5
Depositing dilute atomic ensembles onto cold samples is challenging in low-temperature scanning tunneling microscopes (STM) because radiation shields and restricted internal geomet…
Contactless terahertz mapping of wafer-scale superconducting NbTiN thin films
Yayi Lin, Marc Neis, Marcello Pio Guardascione +9
For large-scale superconducting quantum technology, e.g. quantum computing, the homogeneity of wafer-scale superconducting thin films is vital for consistent performance of the fab…
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…
Subcycle videography of lightwave-driven Landau-Zener-Majorana transitions in graphene
Vincent Eggers, Giacomo Inzani, Manuel Meierhofer +14
Strong light fields have unlocked previously unthinkable possibilities to tailor coherent electron trajectories, engineer band structures and shape emergent phases of matter all-op…
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…
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…
Bond-resolved STM with density-based methods
Emiliano Ventura-Macias, Jose Martinez-Castro, Guillermo Haas +7
Bond-resolved scanning tunneling microscopy (BRSTM) provides intramolecular contrast with CO-functionalized tips, but its interpretation requires a description of both probe relaxa…
Multi-Orbital Charge Transfer into Nonplanar Cycloarenes Revealed with CO-Functionalized Tips
Anja Haags, Alexander Reichmann, Zilin Ruan +20
On-surface synthesis has allowed for the tuneable preparation of numerous molecular systems with variable properties. Recently, we demonstrated the highly selective synthesis of ke…
Solving the Phase Problem of Diffraction: X-ray Standing Waves Imaging on Bismuthene/SiC(0001)
Niclas Tilgner, Susanne Wolff, Serguei Soubatch +6
The phase retrieval problem is a fundamental shortcoming of all diffraction-based methods, arising from the inability to measure the phase of scattered waves. The (normal incidence…
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…
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…
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…
