X-rays writing/reading of Charge Density Waves in the CuO2 plane of a simple cuprate superconductor
Gaetano Campi, Alessandro Ricci, Nicola Poccia +2
It is now well established that superconductivity in cuprates competes with charge modulations giving electronic phase separation at a nanoscale. More specifically, superconducting…
Optimum inhomogeneity of local lattice distortions in La2CuO4+y
Nicola Poccia, Alessandro Ricci, Gaetano Campi +9
Electronic functionalities in materials from silicon to transition metal oxides are to a large extent controlled by defects and their relative arrangement. Outstanding examples are…
Effect of Ru susbstitution on atomic displacements in the layered SmFe_{1-x}Ru_xAsO_{0.85}F_{0.15} superconductor
A. Iadecola, B. Joseph, L. Simonelli +6
The effect of Ru substitution on the local structure of layered SmFeRuAsOF superconductor has been studied by As - and Sm - edges x-ray-absor…
Spatial inhomogeneity and chiral symmetry of the lattice incommensurate supermodulation in high temperature superconductor Bi2Sr2CaCu2O8+y
Nicola Poccia, Gaetano Campi, Michela Fratini +3
Using scanning micro X-ray diffraction we report a mixed real and reciprocal space visualization of the spatial heterogeneity of the lattice incommensurate supermodulation in singl…
Evolution and Control of Oxygen Order in a Cuprate Superconductor
Nicola Poccia, Michela Fratini, Alessandro Ricci +6
The disposition of defects in metal oxides is a key attribute exploited for applications from fuel cells and catalysts to superconducting devices and memristors. The most typical d…
Scale-free structural organization of oxygen interstitials in La2CuO4+y
Michela Fratini, Nicola Poccia, Alessandro Ricci +4
It is well known that the microstructures of the transition-metal oxides (refs 1-3), including the high-transition-temperature (high-Tc) copper oxide superconductors (refs 4-7), ar…
