Measuring thickness in thin NbN films for superconducting devices
Owen Medeiros, Marco Colangelo, Ilya Charaev +1
We present the use of a commercially available fixed-angle multi-wavelength ellipsometer for quickly measuring the thickness of NbN thin films for the fabrication and performance i…
Enhancement of optical response in nanowires by negative-tone PMMA lithography
Ilya Charaev, Andrew Dane, Akshay Agarwal +1
The method of negative-tone-PMMA electron-beam lithography is investigated to improve the performance of nanowire-based superconducting detectors. Using this approach, the supercon…
Magnetic-field enhancement of performance of superconducting nanowire single-photon detector
Ilya Charaev, Alexei Semenov, Konstantin Ilin +1
We present SNSPDs from NbN nanowires shaped after square-spiral that allows an increase not only in critical currents but also an extension of spectral detection efficiencies by ju…
Terahertz Transition-Edge Sensor with Kinetic-Inductance Amplifier at 4.2 K
Artem Kuzmin, Steffen Doerner, Stefan Singer +4
Different terrestrial terahertz applications would benefit from large-format arrays, operating in compact and inexpensive cryocoolers at liquid helium temperature with sensitivity,…
