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…
Accurate measurement of energy relaxation via flux-flow instability
E. M. Baeva, N. A. Titova, M. A. Kirsanova +5
In this paper, we investigate flux-flow instability (FFI) in a superconducting single-crystal titanium nitride (TiN) film with negligible volume pinning. By studying the critical c…
Natural width of the superconducting transition in epitaxial TiN films
E. M. Baeva, A. I. Kolbatova, N. A. Titova +7
We investigate the effect of various fluctuation mechanisms on the DC resistance in superconducting devices based on epitaxial titanium nitride (TiN) films. The samples we studied…
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…
