Researchers at Leti have come up with a way to connect a home’s electric heating system to France’s national grid, letting homeowners take advantage of off-peak utility rates without sacrificing comfort. This smart-grid solution comes in the form of a dedicated circuit board with its own microcontroller. The circuit board collects data like peak and […] >>

In June, IMEP-LAHC signed a renewable nine-month contract with Anritsu to use the manufacturer’s state-of-the-art very wideband network analyzer. The analyzer can measure systems from 70 kHz to 145 GHz in a single sweep, achieving never before seen levels of performance and accuracy. The analyzer also has a four ports under probe configuration, offering unparalleled […] >>

Single-electron transistors (SETs) measuring just a few nanometers have been made by several teams of researchers around the world. However, none had managed to do it on CMOS and achieve operation at ambient temperature. Researchers from Leti and INAC have been successful on both fronts, with a transistor inside a 3.4 nm diameter silicon nanowire […] >>

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 […] >>
