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…
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…
Thermal reconstruction as a method of substrate preparation for highly crystalline superconducting TiN resonators
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…
