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…
Superconducting nanowire single-photon detector with integrated impedance-matching taper
Di Zhu, Marco Colangelo, Boris A. Korzh +11
Conventional readout of a superconducting nanowire single-photon detector (SNSPD) sets an upper bound on the output voltage to be the product of the bias current and the load imped…
Jitter Characterization of a Dual-Readout SNSPD
D. F. Santavicca, B. Noble, C. Kilgore +4
To better understand the origins of the timing resolution, also known as jitter, of superconducting nanowire single-photon detectors (SNSPDs), we have performed timing characteriza…
Bridging the gap between nanowires and Josephson junctions: a superconducting device based on controlled fluxon transfer across nanowires
Emily Toomey, Murat Onen, Marco Colangelo +3
The basis for superconducting electronics can broadly be divided between two technologies: the Josephson junction and the superconducting nanowire. While the Josephson junction (JJ…
