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…
