Disorder induced superconducting ratchet effect in nanowires
Shachaf Poran, Efrat Shimshoni, Aviad Frydman
A dc voltage drop develops along amorphous indium oxide nanowires that are exposed to an ac bias source. This voltage is anti-symmetric with magnetic field and is characterized by…
Superconductor-Insulator Magneto-Oscillations in Superconducting Strips
Yeshayahu Atzmon, Efrat Shimshoni
The magnetoresistance of thin superconducting strips subject to a perpendicular magnetic field B and low temperatures T manifests a sequence of alternating superconductor-insulator…
Reset dynamics and latching in niobium superconducting nanowire single-photon detectors
Anthony J. Annunziata, Orlando Quaranta, Daniel F. Santavicca +8
We study the reset dynamics of niobium (Nb) superconducting nanowire single-photon detectors (SNSPDs) using experimental measurements and numerical simulations. The numerical simul…
Tunable superconducting nanoinductors
Anthony J Annunziata, Daniel F Santavicca, Luigi Frunzio +4
We characterize inductors fabricated from ultra-thin, approximately 100 nm wide strips of niobium (Nb) and niobium nitride (NbN). These nanowires have a large kinetic inductance in…
