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…
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…
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…
