Decoding Superconductivity in LaNiO Thin Films via Ozone-Driven Structure and Oxidation Tuning
Mathieu Flavenot, Hoshang Sahib, Jérôme Robert +6
The discovery of superconductivity in bulk Ruddlesden-Popper LaNiO(LNO327) under high hydrostatic pressure has redefined the recent experimental consensus that nickelat…
A metallic CrS phase bridging the gap between two- and three-dimensional dichalcogenides
Hicham Moutaabbid, Dario Taverna, Denis Pelloquin +5
We report on the high-pressure synthesis of a CrS phase in the form of single-crystalline nanorods. A structural refinement of Precession Electron Diffraction Tomography data c…
Tailoring the breathing-mode distortions in nickelate-ferroelectric heterostructures
Guillaume Krieger, Chia-Ping Su, Hoshang Sahib +5
In transition metal oxides electron-electron interaction and lattice degree of freedom are basic ingredients of emergent phenomena, such as metal-to-insulator transition (MIT) and…
Achieving superconductivity in infinite-layer nickelate thin films by aluminum sputtering deposition
Dongxin Zhang, Aravind Raji, Luis M. Vicente-Arche +3
The recent discovery of superconductivity in infinite-layer (IL, ABO) nickelates has opened a new avenue to deepen the understanding of high-temperature superconductivity. Howe…
Polarization boost and ferroelectricity down to one unit cell in layered Carpy-Galy LaTiO thin films
Elzbieta Gradauskaite, Anouk S. Goossens, Xiaoyan Li +4
Layered perovskite-based compounds offer a range of unconventional properties enabled by their naturally anisotropic structure. While most renowned for the superconductivity observ…
Superconductivity in PrNiO2 infinite-layer nickelates
Hoshang Sahib, Francesco Rosa, Aravind Raji +6
Several reports about infinite-layer nickelate thin films suggest that the superconducting critical temperature versus chemical doping phase diagram has a dome-like shape, similar…
