Superfluid response of two-dimensional filamentary superconductors
Giulia Venditti, Ilaria Maccari, Alexis Jouan +7
Different classes of low-dimensional superconducting systems exhibit an inhomogeneous filamentary superconducting condensate whose macroscopic coherence still needs to be fully inv…
Josephson Junctions Via Anodization of Epitaxial Al on an InAs Heterostructure
A. Jouan, J. D. S. Witt, G. C. Gardner +5
We combine electron beam lithography and masked anodization of epitaxial aluminium to define tunnel junctions via selective oxidation, alleviating the need for wet-etch processing…
Origin of the dome-shaped superconducting phase diagram in -based interfaces
A. Jouan, S. Hurand, G. Singh +8
A dome-shaped phase diagram of superconducting critical temperature upon doping is often considered as a hallmark of unconventional superconductors. This behavior, observed in two-…
Single-band to two-band superconductivity transition in two-dimensional oxide interfaces
G. Singh, A. Jouan, G. Herranz +10
In multiorbital materials, superconductivity can exhibit new exotic forms that include several coupled condensates. In this context, quantum confinement in two-dimensional supercon…
Ion irradiated YBa2Cu3O7 nano-meanders for superconducting single photon detectors
P. Amari, C. Feuillet-Palma, A. Jouan +8
We report the fabrication of few hundred microns long, hundreds of nanometers wide and 30 nm thick meanders made from YBa2CU3O7. Thin films protected by a 8 nm-thick Ce02 cap layer…
Effect of disorder on superconductivity and Rashba spin-orbit coupling in LaAlO3/SrTiO3 interfaces
G. Singh, A. Jouan, S. Hurand +6
A rather unique feature of the two-dimensional electron gas (2-DEG) formed at the interface between the two insulators LaAlO3 and SrTiO3 is to host both gate-tunable superconductiv…
Density driven fluctuations in a two-dimensional superconductor
S. Hurand, J. Biscaras, N. Bergeal +11
In the vicinity of a phase transition, the order parameter starts fluctuating before vanishing at the critical point. The fluctuation regime, i.e. the way the ordered phase disappe…
Field-effect control of superconductivity and Rashba spin-orbit coupling in top-gated LaAlO3/SrTiO3 devices
S. Hurand, A. Jouan, C. Feuillet-Palma +13
The recent development in the fabrication of artificial oxide heterostructures opens new avenues in the field of quantum materials by enabling the manipulation of the charge, spin…
