Nano-mapping phase transitions in electronic materials
Scientists at EPFL and the University of Geneva have combined two powerful, cutting-edge techniques to uncover the physics behind an exotic phase transition that turns a metal into an insulator. The materials they looked at are rare-earth nickelates, which are of great interest for innovating new...
Nature Materials – Artificial materials for more efficient electronics
We report on a coupling without physical deformation of chemical bonds that, instead, stems from pure energetic considerations. From today available online in Nature Materials.
News and Views article for Nature
Stefano has written a News and Views article for Nature on a fascinating spintronics work by our colleagues in Grenoble and Paris.
Scanning near-field optical microscopy of LaAlO3/SrTiO3 heterostructures
The interface between LaAlO3 and SrTiO3 hosts a conducting two dimensional electron system with many interesting properties. Since its discovery in 2004, this system has been intensively studied but there are still several open questions mainly related to the presence of local modulations of the...
Spectroscopy of Complex Oxide Interfaces
Some past and present members of our group have contributed to a book, “Spectroscopy of Complex Oxide Interfaces”. Out now!
The complex effect of strain on the structure of perovskite vanadates
Scilight from AIP Publishing is talking about a recent publication of Hugo Meley and coworkers in APL Materials.
Review in Reports On Progress in Physics
Today we had our review “Rare Earth Nickelates RNiO3: Thin Films and Heterostructures” published in Reports on Progress in Physics.
News and views Nature physics
The latest volume of Nature Physics features a News and Views article from Jean-Marc and our collaborator Marc Gabay on the coexistence of superconductivity and ferroelectric-like physics.
Selectively conductive or insulating
Some materials hold surprising — and possibly useful — properties: Neodymium nickel oxide is either a metal or an insulator, depending on temperature. This characteristic makes the material a potential candidate for transistors in modern electronic devices. To understand how neodymium nickel...
A positive step towards negative capacitance – towards more energy-efficient transistors
An international collaboration involving researchers from the University of Geneva, and colleagues from England, Spain, France and Luxembourg has demonstrated that destabilising the spontaneous polarisation of a special class of materials known as ferroelectrics gives rise to the phenomenon of...
Generation of « tailored » magnetic materials
Every day, new technologies require more precision in the intrinsic properties of the materials used. To meet increasingly specific requirements, physicists are interested in a generation of artificial materials, the properties of which can be controlled. Researchers at the University of Geneva...
Researchers explore ultrafast control of magnetism across interfaces
The Geneva team of Prof. Jean-Marc Triscone is well known for the high quality oxide materials that they can synthesize in thin film form with nanoscale control.
Converting heat into electrical energy: a giant leap for oxides
An Italian-Swiss study just published in 'Nature Communications' reveals how some artificial materials composed of different oxides are able to convert heat into electricity with unprecedented efficiency. This work uncovered by researchers from the Universities of Genoa and Geneva, in...
