New magnetic tunnel junctions get encouraging results

Flip-flops are data storage elements used in integrated circuits. And while flip-flops are good, non-volatile flip-flops are even better! The latest generation of magnetic tunnel junctions (MTJs), known as spin-orbit torque (SOT) MTJs, could be the key, delivering crucial speed, energy...

MIT chooses Leti to supply suspended microresonators

The news dates back to early 2014 and has been kept under wraps for almost a year. A Massachusetts Institute of Technology biology lab is turning to Leti to develop some highly complex suspended microresonators. After receiving the initial components, which delivered satisfactory performance, the lab decided to switch foundries, and has now placed an order for 1,500 of the resonators with Leti for June.
The resonators boast a beam that vibrates at several hundred kHz and microfluidic channels through which cells flow. The frequency varies depending on the cells’ mass, which can be measured accurately down to the femtogram (10-15...

Interview

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...

When sol-gel films present inhomogeneities

Thin films formed by sol-gel synthesis are not, in fact, homogeneous! Researchers at Liten’s INAC made the discovery observing an InGaZnO thin film at the ESRF, where x-ray microscopy and grazing-incidence small-angle scattering revealed the formation of mesopores and self-assembled nanometric...

Electrical current circulates in silicon nanonets

Many scientists said it wasn’t possible, but PhD research supervised by LTM and LMGP recently proved the naysayers wrong, demonstrating that electrical current does, in fact, flow through silicon nanonets, unorganized networks of silicon nanowires. The research also looked at a...
