An Irig team, working alongside Polish researchers*, has successfully synthesized and characterized controlled-thickness, highly stable, nanometric zinc oxide (ZnO) nanoplatelets. These nanoplatelets may offer an alternative to classic cadmium chalcogenide 2D nanostructures in optoelectronics. Cadmium chalcogenide is toxic and rare, and its use is tightly regulated by a European directive. Irig researchers studied 2D ZnO […] >>

Researchers from Irig, LTM, and CEA-Leti have developed an almost-instant means of testing bacteria viability after a thermic shock. The new device features an optical nanocavity and two micromirrors. A laser beam bounces back and forth between the mirrors hundreds, or even thousands, of times before escaping: This resonance creates a gradient force* that attracts […] >>

In September, Valeo and CEA-Leti signed a power electronics partnership. Their goal is to optimize the EV powertrain, which encompasses the battery, motor, wheels, and a variety of components in between. The partners’ aim is to improve energy yields while reducing size, weight, and cost. Further priorities include reliability improvements and eco-design: When you add […] >>

Skyrmions are in the news again, thanks to an advance made by a Spintec team, in conjunction with two other laboratories*. The researchers successfully controlled the movement of skyrmions—quasi-particles with potential applications for magnetic memories—in situ by applying a gate voltage to reverse their chirality, or spin direction. This is an important step towards controlling […] >>

A CEA-Leti team has designed an ultra-low-power radiofrequency chip that connects fixed or mobile IoT devices to nanosatellites manufactured by the Swiss company Astrocast. Terrestrial IoT networks cover a mere 15% of the planet’s surface, meaning that this new technology is desperately needed in industries such as maritime transportation, fishing, and offshore oil, which operate […] >>
