Probing thermalization and dynamics of high-energy quasiparticles in a superconducting nanowire by scanning critical current microscopy
T. Jalabert, E. F . C. Driessen, F. Gustavo +3
Besides its fundamental interest, understanding the dynamics of pair breaking in superconducting nanostructures is a central issue to optimize the performances of superconducting d…
How to induce superconductivity in epitaxial graphene remote proximity effect through an intercalated gold layer
Estelle Mazaleyrat, Sergio Vlaic, Alexandre Artaud +12
Graphene holds promises for exploring exotic superconductivity with Dirac-like fermions. Making graphene a superconductor at large scales is however a long-lasting challenge. A pos…
Microwave response and electrical transport studies of disordered s wave superconductor: NbN thin films
D. Hazra, S. Jebari, R. Albert +4
It is now well known that the properties of the disordered s wave superconductors can deviate significantly from the prediction of standard Bardeen-Cooper-Schrieffer (BCS) theory.…
Collective energy gap of preformed Cooper-pairs in disordered superconductors
Thomas Dubouchet, Benjamin Sacépé, Johanna Seidemann +3
In most superconductors the transition to the superconducting state is driven by the binding of electrons into Cooper-pairs. The condensation of these pairs into a single, phase co…
The role of Coulomb interaction in superconducting NbTiN thin films
D. Hazra, N. Tsavdaris, A. Mukhtarova +9
We report on the superconducting properties of NbTiN thin films of thickness 10 nm, with different Ti fraction in the range , deposited b…
Superconducting properties of very high quality NbN thin films grown by high temperature chemical vapor deposition
D. Hazra, N. Tsavdaris, S. Jebari +6
Niobium nitride (NbN) is widely used in high-frequency superconducting electronics circuits because it has one of the highest superconducting transition temperatures ( …
High field termination of a Cooper-pair insulator
B. Sacepe, J. Seidemann, M. Ovadia +5
We conducted a systematic study of the disorder dependence of the termination of superconductivity, at high magnetic fields (B), of amorphous indium oxide films. Our lower disorder…
Electrodynamic response and local tunnelling spectroscopy of strongly disordered superconducting TiN films
P. C. J. J. Coumou, E. F. C. Driessen, J. Bueno +2
We have studied the electrodynamic response of strongly disordered superconducting TiN films using microwave resonators, where the disordered superconductor is the resonating eleme…
Localization of preformed Cooper-pairs in disordered superconductors
B. Sacepe, T. Dubouchet, C. Chapelier +5
The most profound effect of disorder on electronic systems is the localization of the electrons transforming an otherwise metallic system into an insulator. If the metal is also a…
Pseudogap in a thin film of a conventional superconductor
B. Sacepe, C. Chapelier, T. I. Baturina +3
A superconducting state is characterized by the gap in the electronic density of states which vanishes at the superconducting transition temperature Tc. It was discovered that in h…
Tunneling Spectroscopy and Vortex Imaging in Boron-Doped Diamond
B. Sacepe, C. Chapelier, C. Marcenat +4
We present the first scanning tunneling spectroscopy study of single-crystalline boron doped diamond. The measurements were performed below 100 mK with a low temperature scanning t…
Anomalous proximity effect in an inhomogeneous disordered superconductor
W. Escoffier, C. Chapelier, N. Hadacek +1
By combining very low temperature scanning tunneling microscopy and spectroscopy on a TiN film we have observed a non uniform state comprising of superconducting (S) and normal (N)…
