CEA-Leti and CEA-Liten are joining forces to develop a low-loss inverter to boost photovoltaic solar panel conversion efficiency. Inverters transform the direct current PV panel output into alternating current compatible with domestic electricity networks.The new inverter is built on 100V and 650V GaN on silicon power transistors. It is faster (150 kHz) and cuts losses […] >>

UTe2 , which confounds a 60-year-old theory of superconductivity, has captured the scientific community’s attention ever since it was discovered in 2018.Researchers at Irig have now determined that a much stronger than normal magnetic field is required to destroy UTe2 ’s superconductivity.Even more surprising is that the material’s superconductivity actually gets stronger under magnetic fields […] >>

Radiological diagnostics, which include X-ray and other imaging techniques, can be a challenge if a patient cannot be transported or is located far from a medical imaging facility.A Thales-led project involving CEA-Leti to develop mobile point-of-care radiology solutions recently obtained French government funding*.The project consortium is investigating a lightweight, ergonomic X-ray machine and a mobile […] >>

Researchers at Irig achieved a world first when they grew Fe5GeTe2 thin films on sapphire using molecular-beam epitaxy.They were able to obtain a single-crystal two-dimensional material with controlled composition. Here, the simple bilayer boasts ferromagnetic ordering at temperatures up to 229 K, compared to under 100 K for most 2D magnets made using mechanical exfoliation.France’s […] >>

CEA-Leti developed some truly exceptional wireless vibration and temperature sensors for the EU H2020 PreCoM project on decision support for predictive maintenance.The sensors were tested on ten-meter-high machine tools used to manufacture wind-turbine hubs.With power consumption of just 10 µwatts in sleep mode and 10 mW to 15 mW when awake, the sensors are extremely […] >>
