The current understanding of the superconductor–insulator transition is discussed level by
level in a cyclic spiral-like manner. At the first level, physical phenomena and processes are …

Scanning tunneling spectroscopy at very low temperatures on homogeneously disordered
superconducting titanium nitride thin films reveals strong spatial inhomogeneities of the …

Superconducting thin films with high intrinsic kinetic inductance are of great importance for
photon detectors, achieving strong coupling in hybrid systems, and protected qubits. We …

Using a dual-mode STM-AFM microscope operating below 50 mK we measured the local
density of states along small normal wires connected at both ends to superconductors with …

A superconducting state is characterized by the gap in the electronic density of states, which
vanishes at the superconducting transition temperature T c. It was discovered that in high …

Closed-loop optimization of epitaxial titanium nitride (TiN) thin-film growth was
accomplished using metal-organic molecular beam epitaxy (MO-MBE) combined with a …

We demonstrate single-photon counting at 1550 nm with titanium-nitride (TiN) microwave
kinetic inductance detectors. Full-width-at-half-maximum energy resolution of 0.4 eV is …

We present a combined experimental and theoretical study of the proximity effect in an
atomic-scale controlled junction between two different superconductors. Elaborated on a Si …

The proximity effect between a superconductor and a highly diffusive two-dimensional metal
is revealed in a scanning tunneling spectroscopy experiment. The in situ elaborated …

Using a self-consistent Bogoliubov–de Gennes approach, we theoretically study the
proximity-induced density of states (DOS) in clean SFF spin valves with noncollinear …
