Record high-field superconductivity in MgB2: new perspectives for magnet technology

The quest for energy-efficient high-field magnets passes through the progress made on practical superconductors. Scientists from the Department of Quantum Matter Physics (UNIGE), the Laboratory of Advanced Technology – LTA (UNIGE, HES-SO Genève), and the Laboratoire des Champs Magnétiques Intenses of Grenoble (F) have recently shed light on the mechanisms that enhance the upper critical…

Making disorder for an ideal battery

Making disorder for an ideal battery

Manufacturing safer, more powerful batteries that use geopolitically stable resources requires solid electrolytes and replacing lithium with sodium. A chemical solution is now being offered to battery developers. The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks. The electrolyte – the medium that enables electrons and positive charges to…

Superconductivity with a twist explained

Superconductivity with a twist explained

Physicists have revealed what makes magic angle graphene so special. This is a key step elucidating the mystery behind superconductivity in this recently discovered material with potential for technological breakthroughs. Magic-angle materials represent a surprising recent physics discovery in double layers of graphene, the two-dimensional material made of carbon atoms in a hexagonal pattern. When…

Artificial materials for more efficient electronics

Artificial materials for more efficient electronics

The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing “made-to-order” materials and more energy-efficient electronics. We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like….

Irene Cucchi presents her thesis … in comics

Irene Cucchi successfully defended her thesis at the DQMP, UNIGE. For several years, she has been conducting research in a new field of materials physics, at the crossroads of two major advances in condensed matter physics: the discovery of two-dimensional crystals and the discovery of topological insulators. In order to share part of her PhD…

A breach in the “standard model” of quantum matter

A breach in the “standard model” of quantum matter

Professor Dirk van der Marel’s team from the Department of Quantum Matter Physics (DQMP) of Geneva University recently discovered a whole new effect in a magnetic material with a chemical composition of Nd2Ir2O7. At absolute zero (-273.15 degrees Celsius), this material is insulating but by increasing its temperature it becomes an electrical conductor. More precisely,…

Crystallography helps to combat the SARS-CoV-2 virus

The crystal structure of a drug tested against Covid-19 was solved using Fox computer program, developed in the Laboratory of crystallography at the Department of quantum matter physics (DQMP), UNIGE. Recently, a team of researchers from the Illinois Institute of Technology, North Central College and the International Centre for Diffraction Data (ICDD) has reported the…

The LTA contributes to the research on the Covid-19

The LTA contributes to the research on the Covid-19

To achieve optimal virus detection – such as the Covid-19 – using surface plasmon resonance (SPR), a leading SPR manufacturer is relying on glass prisms with a high-quality gold thin film sensor custom grown in the LTA laboratory (Fig.1).    Optical biosensors based on SPR – a high sensitive optical method of analysis – enable…

Creating custom light using 2D materials

Creating custom light using 2D materials

Researchers from UNIGE and the University of Manchester have discovered structures based on two-dimensional materials that emit tailor-made light in any colour you could wish for. Finding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs…
