Researchers from CEA-Leti and CEA-Liten built and tested innovative thermal sensors to monitor the temperature of gallium nitride (GaN) HEMT power components. The sensors are fabricated at the same time and on the same substrate as the components and do not require additional process steps (masks). They utilize the Seebeck effect to predict overheating that […] >>

The purpose of the UNITE! (University Network for Innovation, Technology and Engineering) program is to create a physical and virtual university network across Europe from Finland to Portugal. UNITE! was selected as one of the 17 European University Alliances to receive funding from the European Commission. Grenoble INP-UGA, Institute of Engineering and Management is one […] >>

III-V semiconductor materials are expensive and increasingly rare. Their replacement as the go-to material for lasers is inevitable. CEA-Leti researchers were part of an international team* that recently published a notable advance in Nature Photonics. They developed an optically-pumped IV-IV semiconductor device capable of producing a 2.5 micron laser beam with an ultra-low threshold at […] >>

Researchers from Irig are working on the international LiteBIRD space observation satellite project.  They have been tasked with developing a cold machine that can deliver 2 microwatts at 100 mK—a level of performance never before achieved in space. The cold machine will be used on the two telescopes in the payload. The researchers have opted […] >>

Could all-natural materials be used to make antimicrobial dressings for open, infected wounds? A PhD research project conducted at CEA-Leti, CERMAV, and LGP2 investigated precisely this kind of environmentally-friendly dressing for inpatient care scenarios, and the findings were encouraging. The dressings studied here were made from nanocellulose obtained from wood. The material can take the […] >>
