Superconductivity behavior in epitaxial TiN films points at surface magnetic disorder
N. A. Saveskul, N. A. Titova, E. M. Baeva +11
We analyze the evolution of the normal and superconducting electronic properties in epitaxial TiN films, characterized by high Ioffe-Regel parameter values, as a function of the fi…
Thermal properties of NbN single-photon detectors
E. M. Baeva, M. V. Sidorova, A. A. Korneev +9
We investigate thermal properties of a NbN single-photon detector capable of unit internal detection efficiency. Using an independent calibration of the coupling losses we determin…
Optical single photon detection in micron-scaled NbN bridges
Y. Korneeva, D. Yu. Vodolazov, A. V. Semenov +6
We demonstrate experimentally that single photon detection can be achieved in micron-wide NbN bridges, with widths ranging from 0.53 m to 5.15 m and for photon-wavelengths fr…
Relaxation of the resistive superconducting state in boron-doped diamond films
A. Kardakova, A. Shishkin, A. Semenov +8
We report a study of the relaxation time of the restoration of the resistive superconducting state in single crystalline boron-doped diamond using amplitude-modulated absorption of…
