Leti recently cut the energy requirement of a femtocell base station’s radiofrequency transmission head by 20% to 40%, for a power output of more than 30 dBm. The EU project behind this development was carried out in association with Telecom Italia, Alcatel-Lucent, and Ericsson. The use of a dual-input antenna with excellent isolation properties plus […] >>

After years of research on monomolecular magnets (also called magnetic molecules), scientists have renewed hope that such molecules could one day be used to develop molecular-scale memories. Researchers at INAC recently built a wheel-shaped molecular (uranium-manganese) structure whose hysteresis cycle and energy barrier could be compatible with the applications being targeted. However, these properties were […] >>

Leti researchers recently filed three patents for vibration energy harvesting microsystems. Their new technology counters one of the weaknesses of vibration energy harvesting systems: the systems’ yields drop off sharply when their resonance frequency deviates from the ambient vibration frequency. Currently, the best systems can tolerate vibration frequency differences of just 5%. But the first […] >>

We could one day see electronic components that combine electric and magnetic currents. A Grenoble-based team of researchers from INAC, UJF, Crocus, CNRS, and Thales has just made a step toward this potential breakthrough. The researchers injected spin-polarized electrons into germanium, a material compatible with microelectronics applications, at room temperature. They used a tunnel junction […] >>

Germanium-Antimony-Tellurium, or GST, is a phase-change material that passes from an amorphous to a crystalline state at temperatures of 100°C to 150°C, making it a good candidate for phase-change memory. However, when looking at GST samples under a transmission microscope, scientists observed that these properties actually turn into a disadvantage. During the ion-beam preparation phase, […] >>
