Low-temperature electron dephasing rates indicate magnetic disorder in superconducting TiN films
A. I. Lomakin, E. M. Baeva, N. A. Titova +8
We investigate electron transport and phase-breaking processes in thin titanium nitride (TiN) films of epitaxial quality. Previous studies show that a minute surface magnetic disor…
Evidence of the disorder-independent electron-phonon scattering time in thin NbN films
A. I. Lomakin, E. M. Baeva, A. D. Triznova +7
We report on experimental study of the effect of disorder on electronic parameters and inelastic scattering mechanisms in ultrathin superconducting NbN films, which are commonly us…
Slow electron-phonon relaxation controls the dynamics of the superconducting resistive transition
E. M. Baeva, A. I. Kolbatova, N. A. Titova +8
We investigate the temporal and spatial scales of resistance fluctuations (-fluctuations) at the superconducting resistive transition accessed through voltage fluctuations measu…
Magnetoconductance and photoresponse properties of disordered NbTiN films
M. Sidorova, A. Semenov, H. -W. Huebers +4
We report on the study of phonon properties and electron-phonon coupling in thin NbTiN films, which are intensively exploited in superconducting devices. Studied NbTiN films with t…
Superconductivity behavior in epitaxial TiN films points at surface magnetic disorder
N. A. Saveskul, N. A. Titova, E. M. Baeva +11
We analyze the evolution of the normal and superconducting electronic properties in epitaxial TiN films, characterized by high Ioffe-Regel parameter values, as a function of the fi…
Thermal properties of NbN single-photon detectors
E. M. Baeva, M. V. Sidorova, A. A. Korneev +9
We investigate thermal properties of a NbN single-photon detector capable of unit internal detection efficiency. Using an independent calibration of the coupling losses we determin…
Optical single photon detection in micron-scaled NbN bridges
Y. Korneeva, D. Yu. Vodolazov, A. V. Semenov +6
We demonstrate experimentally that single photon detection can be achieved in micron-wide NbN bridges, with widths ranging from 0.53 m to 5.15 m and for photon-wavelengths fr…
Superconducting fluctuations and characteristic time scales in amorphous WSi
Xiaofu Zhang, Adriana E. Lita, Mariia Sidorova +5
We study magnitudes and temperature dependences of the electron-electron and electron-phonon interaction times which play the dominant role in the formation and relaxation of photo…
Non-bolometric bottleneck in electron-phonon relaxation in ultra-thin WSi film
M. Sidorova, A. Kozorezov, A. Semenov +6
We developed the model of the internal phonon bottleneck to describe the energy exchange between the acoustically soft ultrathin metal film and acoustically rigid substrate. Discri…
Relaxation of the resistive superconducting state in boron-doped diamond films
A. Kardakova, A. Shishkin, A. Semenov +8
We report a study of the relaxation time of the restoration of the resistive superconducting state in single crystalline boron-doped diamond using amplitude-modulated absorption of…
Vortex assisted mechanism of photon counting in superconducting nanowire single photon detector revealed by external magnetic field
D. Yu. Vodolazov, Yu. P. Korneeva, A. V. Semenov +2
We use external magnetic field to probe the detection mechanism of superconducting nanowire single photon detector. We argue that the hot belt model (which assumes partial suppress…
Coherent Flux Tunneling Through NbN Nanowires
J. T. Peltonen, O. V. Astafiev, Yu. P. Korneeva +8
We demonstrate evidence of coherent magnetic flux tunneling through superconducting nanowires patterned in a thin highly disordered NbN film. The phenomenon is revealed as a superp…
