Different single photon response of wide and narrow superconducting MoSi strips
Yu. Korneeva, N. Manova, I. Florya +4
The photon count rate of superconducting single photon detectors made of MoSi films shaped as a m-wide strip and a 115 nm-wide meander stripline is studied experimentally as…
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…
Quasi-1-Dimensional Superconductivity in Highly Disordered NbN Nanowires
K. Yu. Arutyunov, A. Ramos-Álvarez, A. V. Semenov +6
The topic of superconductivity in strongly disordered materials has attracted a significant attention. In particular vivid debates are related to the subject of intrinsic spatial i…
Vortex assisted mechanism of photon counting in superconducting nanowire single photon detector revealed by external magnetic field
D. Yu. Vodolazov, Yu. P. Korneeva, A. V. Semenov +2
We use external magnetic field to probe the detection mechanism of superconducting nanowire single photon detector. We argue that the hot belt model (which assumes partial suppress…
Dark counts initiated by macroscopic quantum tunneling in NbN superconducting photon detectors
A. Murphy, A. Semenov, A. Korneev +3
We perform measurements of the switching current distributions of three w = 120 nm wide, 4 nm thick NbN superconducting strips which are used for single-photon detectors. These str…
Superconducting single-photon detector made of MoSi film
Yu. P. Korneeva, M. Yu. Mikhailov, Yu. P. Pershin +8
We fabricated and characterised nanowire superconducting single-photon detectors (SSPDs) made of 4 nm thick amorphous MoSi films. At 1.7 K the best devices exhibit a de…
