Highlights
The comic book ‘A Passion for Physics’, co-written by GEMaC researcher Marie-Amandine Pinault-Thaury, is now available in English! July 16, 2025 The Société Française de Physique's comic book, published in 2023 to mark its 150th anniversary, is now available in English. The book was co-written by Marie-Amandine Pinault-Thaury (CNRS researcher at GEMaC), Isabelle Mirebeau (CNRS researcher at LLB) and Aurélie Bordenave (scientific cartoonist). | |
Pushing the Boundaries of Ga₂O₃ Technology for Energy and Power Electronics through Quantum Disorder June 3, 2025 A new study shows that, through phosphorus doping of β-Ga₂O₃, an exceptional p-type conductivity is obtained at room temperature, as well as a metal-insulator transition. These results open avenues for improving power electronics, essential to power grids and transport systems, and contributes to wider adoption of renewable energies. | |
Efficient, bright single-photon emitters thanks to a silver mirror March 11, 2025 Researchers at GEMaC have coupled a nanometric layer of silver with a 2D material to unlock the secrets of the single-photon sources they have created in this crystal. | |
Decoding the Mysteries of Spin-Crossover Materials: A Model to Explore Complex Phenomena October 23, 2024 Researchers have developed a model inspired by the Ising model to explain a wide range of fascinating behaviours observed in certain spin-crossover materials. Their work made the cover of ChemPhysChem. | |
Blue diamonds to understand spin-orbit interaction April 11, 2024 Very high resolution optical absorption measurements have made it possible to understand the light spectrum of boron-doped synthetic diamond, as part of an international collaboration between GEMaC and Kyoto University (Japan). |
