Universal bottleneck for thermal relaxation in disordered metallic films
E. M. Baeva, N. A. Titova, A. I. Kardakova +2
We study the heat relaxation in current biased metallic films in the regime of strong electron-phonon coupling. A thermal gradient in the direction normal to the film is predicted,…
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…
