Thermal relaxation in metal films limited by diffuson lattice excitations of amorphous substrates
E. M. Baeva, N. A. Titova, L. Veyrat +5
Here we examine the role of the amorphous insulating substrate in the thermal relaxation in thin NbN, InO, and Au/Ni films at temperatures above 5 K. The studied samples are ma…
Charge-neutral nonlocal response in superconductor-InAs nanowire hybrid devices
A. O. Denisov, A. V. Bubis, S. U. Piatrusha +8
Nonlocal quasiparticle transport in normal-superconductor-normal (NSN) hybrid structures probes sub-gap states in the proximity region and is especially attractive in the context o…
Universal bottleneck for thermal relaxation in disordered metallic films
E. M. Baeva, N. A. Titova, A. I. Kardakova +2
We study the heat relaxation in current biased metallic films in the regime of strong electron-phonon coupling. A thermal gradient in the direction normal to the film is predicted,…
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…
