Researchers from Leti, CNRS, LTM, and LPN recently used an Auger probe for the elementary quantitative analysis of a silicon-germanium heterostructure nanowire. But first, they had to develop new spectroscopy and profilometry protocols, which they validated by comparing the results with previous X-ray diffraction and TEM results. The Auger nanoprobe offers several advantages over X-ray […] >>

A team of researchers from INAC and Leti are exploring a variety of processes to deform germanium as much as possible to dope the material’s light-emitting capacity, paving the way for use in laser emission. The team’s latest article focused on the use of a constrained silicon nitride layer to deform germanium nanowires. The nanowires […] >>

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. […] >>
