The tiny magnetic bubbles known as skyrmions—potential candidates for tomorrow’s memory bits—can now be stabilized at ambient temperature without a magnetic field. Researchers at Spintec just demonstrated this new capability using an exchange coupler already used in MRAM. Specifically, an anti-ferromagnetic layer is combined with the ultra-thin ferromagnetic layer that holds the skyrmions.The size of […] >>

Clinatec has been trying to effectively determine the best location in the brain for its WIMAGINE® implant, which measures the brain activity of tetraplegic patients. The data is used to control an exoskeleton, restoring these patients’ mobility and independence. Where to implant the device is a key challenge for Clinatec. Researchers at the center have […] >>

Researchers at CEA-Leti printed a pixelated hologram on a postage-stamp-sized component. The pixels, called “hoels”, are distributed across the entire surface. When illuminated by micro-laser sources, they reconstitute a coherent image on the retina. The innovation is targeting augmented reality glasses, where the hologram would be superimposed on the scene the wearer is looking at.The […] >>

Lattice constant is a measure of how structurally compatible two materials are. Researchers from Irig and Institut Néel recently reduced these differences for GaAs/InAs (gallium arsenide/indium arsenide) nanowires. Their approach was to form a 5 nm ternary (InGaAs) alloy interface between the materials. The alloy’s composition transitions from a composition close to GaAs to one […] >>

How do you reconstruct the C-face of a silicon carbide (SiC) wafer after cutting? The issue has been the subject of great debate since an early observation that dates back to 1997. An international team led by Irig simulated a novel approach to surface reconstruction never before used for semiconductors. The research was published in […] >>
