Théano Karatsori authored nine articles and five conference papers during her PhD research alone. If that wasn’t impressive enough, she also won the EEA* Best Dissertation Award for her work. This bright young woman, now a post-doc at Leti, is certainly doing something right! Her award-winning research on the characterization and modeling of nano-scale (28 […] >>

IRIG and Japan’s University of Tsukuba recently kicked off their second joint PhD research project on the ultra-rapid displacement of magnetic walls using the spin-transfer effect in manganese nitride (Mn4N). The conclusions of an earlier PhD dissertation were promising.  Samples produced in Japan were sent to Grenoble, where they were used to reproducibly displace walls […] >>

Molybdenum diselenide (MoSe2) has good optical properties, but is resistant to deposition processes. Microelectronics researchers had all but given up on the material, but research recently conducted by three physics labs at IRIG could change that. The researchers obtained an unbroken and uniform layer of MoSe2 using molecular beam epitaxy on a graphene substrate. The […] >>

Leti has achieved a world-first in embedded artificial intelligence with its Spirit neural-network-on-chip. The component is largely brain-inspired, using unary rather than binary coding, just like neurons! Each event adds “weight” to the synapse until a “firing” threshold is reached. The chip’s resistive memory is also bio-inspired: Integrating the memory directly on the chip eliminates […] >>

The Tiny lithium-ion microbattery is redefining the international state of the art in miniature energy storage, with a thickness of less than 100 microns, a surface area of just a few square millimeters, and a capacity three times that of competing batteries. Leti and Liten developed Tiny, which is made using a thin-layer deposition technique. […] >>
