On March 1, Daniel Bellet (LMGP, Phelma) succeeded François Weiss as Scientific Director of Institut Carnot Énergies du Futur. He will occupy the position with a co-director from Liten, which is the institute’s coordinator and partner. LMGP is currently overseeing two Carnot projects. The first, called Eco-LED is developing low-cost, high-performance, easy-to-recycle white LEDs that […] >>

Grenoble-based researchers from IRIG working at ESRF successfully obtained a single layer of graphene on single-crystal iridium with a periodicity of 2.5 nm using a CVD reactor. Materials research institute Institut Lumière Matière in Lyon had previously obtained iron-platinum nanoparticles, organized them at the atomic scale, and given them magnetic properties. Here, the two teams […] >>

Researchers at Spintec have come up with a new way to improve MRAM memory retention, using tungsten instead of tantalum in the magnetic tunnel junction stacks. When the stacks are made, they must be annealed to crystallize the junctions. During annealing, the tantalum tends to diffuse toward the tunnel barrier, absorbing oxygen in the process. […] >>

Quantum error-correcting codes were developed by mathematicians to check the variability of the state of each qubit. But are the codes relevant in practical terms? A physicist at IRIG investigated the issue and his conclusions are not optimistic. He noted that the theories use error models that fail to factor in errors that are rare, […] >>

Researchers from LMGP and Leti tested OLEDs developed by Leti for microdisplays for toxicity to determine whether the OLEDs could be used in biological environments. The researchers monitored the growth of two cultures (one cellular and one bacterial) in which an OLED had been placed and compared growth to control cultures. They found that the […] >>
