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…
Proximity effect model of ultra-narrow NbN strips
I. Charaev, T. Silbernagel, B. Bachowsky +7
We show that narrow superconducting strips in superconducting (S) and normal (N) states are universally described by the model presenting them as lateral NSN proximity systems in w…
Enhancement of superconductivity in NbN nanowires by negative electron-beam lithography with positive resist
I. Charaev, T. Silbernagel, B. Bachowsky +7
We performed comparative experimental investigation of superconducting NbN nanowires which were prepared by means of positive-and negative electron-beam lithography with the same p…
