P-type behavior of CrN thin films by control of point defects
Arnaud le Febvrier, Davide Gambino, Fabien Giovannelli +5
We report the results of a combined experimental and theoretical study on nonstoichiometric CrN1+d thin films grown by reactive magnetron sputtering on c-plane sapphire, MgO (100)…
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-…
One MAX phase, different MXenes: a guideline to understand the crucial role of etching conditions on TiCT surface chemistry
Mohamed Benchakar, Lola Loupias, Cyril Garnero +13
MXenes are a new, and growing, family of 2D materials with very promising properties for a wide variety of applications. Obtained from the etching of MAX phases, numerous propertie…
Optical and nanostructural insights of oblique angle deposited layers applied for photononic coatings
Florian Maudet, Bertrand Lacroix, Antonio J. Santos +10
Oblique angle deposition (OAD) is a nanostructuration method widely used to tune the optical properties of thin films. The introduction of porosity controlled by the deposition ang…
On the importance of light scattering for high performances nanostructured antireflective surfaces
Florian Maudet, Bertrand Lacroix, Antonio J. Santos +8
An antireflective coating presenting a continuous refractive index gradient is theoretically better than its discrete counterpart because it can give rise to a perfect broadband tr…
Non-linear characteristics in two-dimensional superconductors: Berezinskii-Kosterlitz-Thouless physics vs inhomogeneity
G. Venditti, J. Biscaras, S. Hurand +9
One of the hallmarks of the Berezinskii-Kosterlitz-Thouless (BKT) transition in two-dimensional (2D) superconductors is the universal jump of the superfluid density, that can be in…
Quantized conductance in a one-dimensional ballistic oxide nanodevice

Electric-field effect control of two-dimensional electron gases (2-DEG) has enabled the exploration of nanoscale electron quantum transport in semiconductors. Beyond these classica…
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…
