Determination of Mid-Infrared Refractive Indices of Superconducting Thin Films Using Fourier Transform Infrared Spectroscopy
Dip Joti Paul, Tony X. Zhou, Karl K. Berggren
In this work, we present a technique to determine the mid-infrared refractive indices of thin superconducting films using Fourier transform infrared spectroscopy (FTIR). In particu…
Large-area microwire MoSi single-photon detectors at 1550 nm wavelength
Ilya Charaev, Yukimi Morimoto, Andrew Dane +3
We demonstrate saturated internal detection efficiency at 1550 nm wavelengths for meander-shaped superconducting nanowire single-photon detectors made of 3 nm thick MoSi films with…
A Power Efficient Artificial Neuron Using Superconducting Nanowires
Emily Toomey, Ken Segall, Karl K. Berggren
With the rising societal demand for more information-processing capacity with lower power consumption, alternative architectures inspired by the parallelism and robustness of the h…
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…
Timing performance of 30-nm-wide superconducting nanowire avalanche photodetectors
F. Najafi, F. Marsili, E. Dauler +2
We investigated the timing jitter of superconducting nanowire avalanche photodetectors (SNAPs, also referred to as cascade switching superconducting single photon detectors) based…
Critical-Current Reduction in Thin Superconducting Wires Due to Current Crowding
H. L. Hortensius, E. F. C. Driessen, T. M. Klapwijk +2
We demonstrate experimentally that the critical current in superconducting NbTiN wires is dependent on their geometrical shape, due to current-crowding effects. Geometric patterns…
Afterpulsing and Instability in Superconducting Nanowire Avalanche Photodetectors
F. Marsili, F. Najafi, E. Dauler +2
We investigated the reset time of superconducting nanowire avalanche photodetectors (SNAPs) based on 30 nm wide nanowires. We studied the dependence of the reset time of SNAPs on t…
