  Title Influence of sputtering parameters on the main characteristics of ultra-thin vanadium nitride films Type Conference Article
  Year 2018 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1124 Issue Pages 051030  
  Keywords (down) SSPD, SNSPD, VN  
  Abstract We researched the relation between deposition and ultra-thin VN films parameters. To conduct the experimental study we varied substrate temperature, Ar and N2 partial pressures and deposition rate. The study allowed us to obtain the films with close to the bulk values transition temperatures and implement such samples in order to fabricate superconducting single-photon detectors.

  Title Electron diffusivity measurements of VN superconducting single-photon detectors Type Conference Article
  Year 2018 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1124 Issue Pages 051032  
  Keywords (down) SSPD, SNSPD, VN  
  Abstract The research of ultrathin vanadium nitride (VN) films as a promising candidate for superconducting single-photon detectors (SSPD) is presented. The electron diffusivity measurements are performed for such devices. Devices that were fabricated out from 9.9 nm films had diffusivity coefficient of 0.41 cm2/s and from 5.4 nm – 0.54 cm2/s. Obtained values are similar to other typical SSPD materials. The diffusivity that increases along with decreasing of the film thickness is expected to allow fabrication of the devices with improved characteristics. Fabricated VN SSPDs showed prominent single-photon response in the range 0.9-1.55 µm.

  Title Однофотонный отклик в тонких сверхпроводящих MoNx пленках Type Conference Article
  Year 2018 Publication Сборн. науч. труд. VII международн. конф. по фотонике и информац. опт. Abbreviated Journal Сборн. науч. труд. VII международн. конф. по фотонике и информац. опт.  
  Volume Issue Pages 408-409  
  Keywords (down) SSPD, SNSPD  
  Abstract Продемонстрирован однофотонный отклик, при токе близком к критическому, в MoNx сверхпроводящих полосках шириной 70-104 нм. MoNx детекторы, имеющие коэффициент диффузии D≈0.32 см2/с и время электрон-фононного взаимодействия ηe-ph≈300 пс, достигают квантовой эффективности QE≈20% на длине волны λ=1550 нм. Возможность реализации однофотонного детектора в данном материале, подтверждает существующую теорию вихревого механизма возникновения фотоотклика в узких сверхпроводящих полосках.

  Title Photon switching statistics in multistrip superconducting single-photon detectors Type Journal Article
  Year 2018 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.  
  Volume 28 Issue 7 Pages 1-4  
  Keywords (down) SSPD, SNSPD  
  Abstract We study photon count statistics in superconducting single-photon detectors consisting of up to 70 narrow superconducting strips connected in parallel. Using interarrival time analysis, we demonstrate that our samples are operated in the “arm-trigger” regime and require up to seven subsequently absorbed photons to form a resistive state in the whole sample. We also performed numerical simulation of the light and dark count rates versus detector bias current, which are in good agreement with the experimental results.

  Title Optical single photon detection in micron-scaled NbN bridges Type Miscellaneous
  Year 2018 Publication arXiv Abbreviated Journal  
  Volume Issue Pages  
  Keywords (down) SSPD  
  Abstract We demonstrate experimentally that single photon detection can be achieved in micron-wide NbN bridges, with widths ranging from 0.53 μm to 5.15 μm and for photon-wavelengths from 408 nm to 1550 nm. The microbridges are biased with a dc current close to the experimental critical current, which is estimated to be about 50 % of the theoretically expected depairing current. These results offer an alternative to the standard superconducting single-photon detectors (SSPDs), based on nanometer scale nanowires implemented in a long meandering structure. The results are consistent with improved theoretical modelling based on the theory of non-equilibrium superconductivity including the vortex-assisted mechanism of initial dissipation.

  Title Single photon detection in micron scale NbN and α-MoSi superconducting strips Type Conference Article
  Year 2018 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume 190 Issue Pages 04010 (1 to 2)  
  Keywords (down) SSPD  
  Abstract We experimentally demonstrate the single photon detection in straight micrometer-wide NbN and α-MoSi bridges. Width of the bridges is 2 µm, while the wavelength of the photon changes from 408 to 1550 nm and critical current exceeds 50% of the depairing current. Obtained results offer the alternative route for design of detectors without resonator and meander structure and indirectly confirm vortex assisted mechanism of single photon detection.
