Highlights

	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).
	Native “imperfections” enables room-temperature p-type conductivity in β-Ga2O3 November 23, 2023 Researchers from GEMaC have demonstrated an important step for the realization of power electronics devices.
	Coherent photons in two dimensions August 25, 2023 Researchers at GEMaC have published two complementary studies demonstrating that single photons emitted by a two-dimensional material are coherent, a property that is essential for applications in quantum computing. This work was the subject of an INP highlight.
