Dissipative phases across the superconductor-to-insulator transition
François Couëdo, Olivier Crauste, Anne-Aëlle Drillien +4
Competing phenomena in low dimensional systems can generate exotic electronic phases, either through symmetry breaking or a non-trivial topology. In two-dimensional (2D) systems, t…
Destruction of superconductivity in disordered materials : a dimensional crossover
O. Crauste, F. Couëdo, L. Bergé +2
The disorder-induced Superconductor-to-Insulator Transition in amorphous NbSi two-dimensional thin films is studied for different niobium compositions through a v…
Effect of annealing on the superconducting properties of a-Nb(x)Si(1-x) thin films
O. Crauste, A. Gentils, F. Couëdo +5
a-Nb(x)Si(1-x) thin films with thicknesses down to 25 Å have been structurally characterized by TEM (Transmission Electron Microscopy) measurements. As-deposited or annealed films…
Tunable Superconducting Properties of a-NbSi Thin Films and Application to Detection in Astrophysics
O. Crauste, C. A. Marrache-Kikuchi, L. Berge +5
We report on the superconducting properties of amorphous NbxSi1-x thin films. The normal-state resistance and critical temperatures can be separately adjusted to suit the desired a…
