Goniometer antennas could soon have embedded monitoring capabilities to make sure that their performance continues to align with factory specifications even after the devices have been installed on a drone or other vehicle. The system, developed under a PhD research project at Leti, uses a network of photodiodes to probe the antennas’ immediate environment. The […] >>

Scientists have known for a long time that the current in a magnetic tunnel junction (MTJ) depends heavily on the spin states at the interfaces between the ferromagnetic and insulating layers. Some states promote the flow of current, while others don’t. However, what scientists didn’t fully understand was why. Until now! An international team that […] >>

Metallizing porous silicon no longer requires a physical process or CVD. Researchers from the CEA and the nanochemistry lab at CPE Lyon have developed a gentle metallization method using a process that is more effective and less costly than current solutions. The porous silicon is immersed in an ionic liquid bath containing an organometallic precursor. […] >>

Patients suffering from Wilson’s disease—which causes copper to accumulate in the liver—could soon benefit from a new, more effective treatment with minimal side effects. Researchers at INAC and DSM (the CEA’s materials science division) have synthesized molecules capable of targeting liver cells to trap the copper. The molecules use coordination sites, much like small proteins […] >>

An international team led by researchers from INAC recently demonstrated that, in SOI transistors, electronic spin alignment under an outside magnetic field is much easier when restricted to a single “valley.” The valley index is a quantum number that shows the relationship between the energy and amount of electron movement within the silicon on a […] >>
