Researchers at Irig collaborated with an international team to obtain dynamic coupling between two magnetic layers (yttrium iron garnet) separated by a gadolinium-gallium garnet substrate. These materials are all very good electrical insulators. The spin information can cross the substrate (which is neither magnetic nor electrically conductive) when the information is carried by chiral photons, […] >>

Leti and SYMME* developed a standout piezoelectric energy harvester. The researchers increased bandwidth by an impressive 446% and achieved near-state-of-the-art total efficiency of 94%. The device’s excellent performance can be attributed to a smart interface that dynamically tunes the resonance frequency to the environment’s vibration frequency. This allows the device to harvest energy beyond what […] >>

Researchers at Irig developed an ultra-fast magnetic tunnel junction (MTJ) that could be used to log events captured by stroboscopic photography. They used a terbium-cobalt layer whose magnetization can be switched using a femtosecond laser. A second magnetic layer is made from a material whose magnetization is not switchable. The magnetizations of these two layers […] >>

Creating photonic circuits that leverage Leti’s 310 nm platform just got easier. Mentor Graphics’ Tanner design flow now includes an integrated Process Design Kit (PDK). The PDK provides access to a library of proven components and can also be used to design new ones. It is also fully compatible with another Mentor Graphics tool that […] >>

Researchers at Irig used a transmission electron microscope to observe the behavior of aluminum (Al) heated to temperatures in excess of 250 °C when it comes into contact with a germanium (Ge) nanowire. So, what did they see? Well, the Al propagates in the nanowire along a well-defined front; the Ge is pushed back and […] >>
