Highly responsive Y-Ba-Cu-O thin film THz detectors with picosecond time resolution
P. Thoma, J. Raasch, A. Scheuring +11
High-temperature superconducting YBa2Cu3O7-d (YBCO) thin-film detectors with improved responsivities were developed for fast time-domain measurements in the THz frequency range. YB…
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…
Infrared photo-response of Fe-shunted Ba-122 thin film microstructures
L. Rehm, D. Henrich, M. Hofherr +10
We present a study of the response to pulsed infrared radiation of Fe-layer shunted pnictide thin film microstructures. The thin film multilayer consisting of 20 nm thick Fe-buffer…
Temperature-dependence of detection efficiency in NbN and TaN SNSPD
Andreas Engel, Kevin Inderbitzin, Andreas Schilling +7
We present systematic measurements of the temperature-dependence of detection efficiencies in TaN and NbN superconducting nanowire single-photon detectors. We have observed a clear…
Broadening of hot-spot response spectrum of superconducting NbN nanowire single-photon detector with reduced nitrogen content
D. Henrich, S. Dörner, M. Hofherr +6
The spectral detection efficiency and the dark count rate of superconducting nanowire single-photon detectors (SNSPD) has been studied systematically on detectors made from thin Nb…
Direct current superconducting quantum interferometers with asymmetric shunt resistors
M. Rudolph, J. Nagel, J. M. Meckbach +5
We have investigated asymmetrically shunted Nb/Al-AlO/Nb direct current (dc) superconducting quantum interference devices (SQUIDs). While keeping the total resistance ident…
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…
