Supercurrent-Controlled Kinetic Inductance Superconducting Memory
Eduard Ilin, Xiangyu Song, Irina Burkova +4
We report superconducting kinetic inductance memory (SKIM) element, which can be controlled exclusively by the bias supercurrent, without involving magnetic fields and heating elem…
Enhancing the Performance of Superconducting Nanowire-Based Detectors with High-Filling Factor by Using Variable Thickness
Reza Baghdadi, Ekkehart Schmidt, Saman Jahani +9
Current crowding at bends of superconducting nanowire single-photon detectors is one of the main factors limiting the performance of meander-style detectors with large filling fact…
Local thermal fluctuations in current-carrying superconducting nanowires
Alexej D. Semenov, Mariia Sidorova, Mikhail A. Skvortsov +3
We analyze the effect of different types of fluctuations in internal electron energy on the rates of dark and photon counts in straight current-carrying superconducting nanowires.…
Electron energy relaxation in disordered superconducting NbN films
Mariia Sidorova, Alexej Semenov, Heinz-Wilhelm Hübers +8
We report on the inelastic-scattering rate of electrons on phonons and relaxation of electron energy studied by means of magnetoconductance, and photoresponse, respectively, in a s…
Spectroscopic evidence for strong correlations between local superconducting gap and local Altshuler-Aronov density-of-states suppression in ultrathin NbN films
C. Carbillet, V. Cherkez, M. A. Skvortsov +10
Disorder has different profound effects on superconducting thin films. For a large variety of materials, increasing disorder reduces electronic screening which enhances electron-el…
Magnetic-field enhancement of performance of superconducting nanowire single-photon detector
Ilya Charaev, Alexei Semenov, Konstantin Ilin +1
We present SNSPDs from NbN nanowires shaped after square-spiral that allows an increase not only in critical currents but also an extension of spectral detection efficiencies by ju…
Superconducting fluctuations in a thin NbN film probed by the Hall effect
Daniel Destraz, Konstantin Ilin, Michael Siegel +2
We present a comprehensive study of how superconducting fluctuations in the normal state contribute to the conductivity tensor in a thin (119 ) film of NbN. It is shown how thes…
NbN/AlN/NbN Josephson junctions on sapphire for receiver applications
M. Merker, C. Bohn, M. Völlinger +2
The most developed integrated receivers for THz radiation nowadays are based on Josephson junction SIS devices. In this kind of devices, the highest receivable frequency is determi…
Sub-μm Josephson Junctions for Superconducting Quantum Devices
J. M. Meckbach, M. Merker, S. J. Buehler +7
For high-performance superconducting quantum devices based on Josephson junctions (JJs) decreasing lateral sizes is of great importance. Fabrication of sub-μm JJs is challenging du…
Break-up of long-range coherence due to phase fluctuations in ultrathin superconducting NbN films
Y. Noat, T. Cren, C. Brun +7
Using scanning tunneling spectroscopy (STS), we address the problem of the superconductor-insulator phase transition (SIT) in homogeneously disordered ultrathin (2-15 nm) films of…
Trapped electron coupled to superconducting devices
P. Bushev, D. Bothner, J. Nagel +8
We propose to couple a trapped single electron to superconducting structures located at a variable distance from the electron. The electron is captured in a cryogenic Penning trap…
Thermal escape of fractional vortices in long Josephson junctions
U. Kienzle, T. Gaber, K. Buckenmaier +5
We consider a fractional Josephson vortex in a long 0-kappa Josephson junction. A uniformly applied bias current exerts a Lorentz force on the vortex. If the bias current exceeds t…
