UV LEDs: could nanowires be the key to efficiency?

UV LEDs produced using the semiconductor material aluminum gallium nitride (AlGaN) in thin layers perform poorly in the brightness and lifespan departments. Researchers on a joint INAC-CNRS team wondered what would happen if they used the material in nanowire form. And,...

2016–2020: FMNT expands

The FMNT (Federation for Micro and Nanotechnologies) saw its mandate renewed for an additional five years on January 1, 2016. The organization took advantage of the occasion to bring in three new labs, bringing its total headcount to nearly 500—a 30% increase. The FMNT is now one of France’s largest research organizations in the fields of microelectronics and nanotechnology. Until end-2015, the FMNT encompassed four labs: LTM, LMGP, IMEP-LaHC, and part of G2ELab’s activities. The new, expanded FMNT is now home to Spintec, two research teams from TIMA, and an additional team from LCIS in Valence.

Five strategic research areas and...

Interview: “Standards will help us position our technologies”,

Dominique Noguet, Head of Communication and Security Technology, Leti, an institute of the CEA
“Standards will help us position our technologies”

Leti has been working on a standard for cognitive radio since 2011. Why?

We developed a cognitive radio technology that leverages TV white space. In other words, it takes advantage of UHF bands allocated to TV broadcasting, but that are not being used locally. If we want to get manufacturers on board with this new technology, there has to be some kind of standard to ensure the compatibility of future products.

Who approves the standard? Is it up to each...
