Current dependence of the hot-spot response spectrum of superconducting single-photon detectors with different layouts
I. Charaev, A. Semenov, S. Doerner +3
We show that avoiding bends in a current-carrying superconducting nanowire enhances the probability for low energy photons to be detected and that this enhancement is entirely due…
Detection Efficiency of a Spiral-Nanowire Superconducting Single-Photon Detector
D. Henrich, L. Rehm, S. Dörner +4
We investigate the detection efficiency of a spiral layout of a Superconducting Nanowire Single-Photon Detector (SNSPD). The design is less susceptible to the critical current redu…
Geometry-induced reduction of the critical current in superconducting nanowires
D. Henrich, P. Reichensperger, M. Hofherr +5
Reduction of the critical current in narrow superconducting NbN lines with sharp and rounded bends with respect to the critical current in straight lines was studied at different t…
Fluctuation effects in superconducting nanostrips
A. Engel, A. D. Semenov, H. -W. Huebers +2
Superconducting fluctuations in long and narrow strips made from ultrathin NbN films, have been investigated. For large bias currents close to the critical current fluctuations led…
