It is now possible to analyze secure-circuit failures at the individual transistor—the ultimate degree of precision. However, to do so requires access to one of the world’s four nanofocused X-ray beams. A team of researchers from CESTI*-Leti used the beamline at Grenoble’s Synchrotron to obtain some original results. The nanofocused beam can put and keep […] >>

The eight partners of the EU PiezoMAT project, coordinated by Leti, achieved resolutions twice as high as what the FBI requires for fingerprint recognition. The project resulted in a prototype fingerprint recognition sensor with 250 pixels 4 microns in diameter; each pixel is made up of a bunch of piezoelectric nanowires on silicon. When a […] >>

Growing indium arsenide (InAs) and gallium arsenide (GaAs) heterostructures is theoretically impossible due to a lattice constant deviation of 6%. However, a team of researchers from INAC and Institut Néel has overcome this hurdle by using the vapor-liquid-solid method to grow nanowires. The vaporized indium and arsenic atoms migrate in a liquid gold nanodroplet located […] >>

It is not very well known exactly why uranium is toxic to or how it interacts with living organisms. A team of researchers at INAC used a biomimetic approach to tackle the issue. The researchers created small peptide sequences that model the protein-metal bonds, and then placed them in contact with uranyl, the uranium ion […] >>

Skyrmions—magnetic bubbles that can be nanometer-sized and that are insensitive to faults—are garnering attention in the spintronics community. They could one day be used as bits in memory or in logic operations. To dig deeper into the issue, researchers from Spintec and Institut Néel recently created the first-ever “skyrmion switch.” The device is made up […] >>
