Compact microwave kinetic inductance nanowire galvanometer for cryogenic detectors at 4.2 K
S. Doerner, A. Kuzmin, K. Graf +3
We present a compact current sensor based on a superconducting microwave lumped-element resonator with a nanowire kinetic inductor, operating at 4.2 K. The sensor is suitable for m…
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…
Characteristics of superconducting tungsten silicide WxSi1-x for single photon detection
X. Zhang, A. Engel, Q. Wang +7
Superconducting properties of three series of amorphous WxSi1-x films with different thickness and stoichiometry were investigated by dc transport measurements in a magnetic field…
Asymmetry in the effect of magnetic field on photon detection and dark counts in bended nanostrips
A. Semenov, I. Charaev, R. Lusche +6
Current crowding in the bends of superconducting nano-structures not only restricts measurable critical current in such structures but also redistributes local probabilities for da…
Superconducting hot-electron nanobolometer with microwave bias and readout
A. A. Kuzmin, M. Merker, S. V. Shitov +7
We propose a new detection technique based on radio-frequency (RF) bias and readout of an antenna-coupled superconducting nanobolometer. This approach is suitable for Frequency-Div…
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…
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…
Non-thermal response of YBCO thin films to picosecond THz pulses
P. Probst, A. Semenov, M. Ries +16
The photoresponse of YBa2Cu3O7-d thin film microbridges with thicknesses between 15 and 50 nm was studied in the optical and terahertz frequency range. The voltage transients in re…
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…
