When two layers of graphene are stacked, even the tiniest misalignment can slow electrons down or bring them to a halt altogether. The underlying physics is particularly rich, with the graphene behaving like a superconductor or, conversely, like an insulator!A recent Irig meta-analysis of around ten studies shed new light on these phenomena. The researchers […] >>

CEA-Leti will present an electronic detonator system with bidirectional radio modules at the Mountain Planet trade show in Grenoble in April.Communicating via a special protocol, the system wirelessly and remotely controls several detonations synchronized to within a tenth of a second, with a success rate of 100%.The technology was originally developed for Davey Bickford, the […] >>

Since September, CEA-Leti and startup Aryballe have been contributing to the European Rose project to design a miniaturized artificial nose.The innovation will help the staggering 20% of the world’s population who have lost or partially lost their sense of smell due to Covid-19 or other illnesses.CEA-Leti is developing ultrasound transducers that contain silicon membranes that […] >>

A recent paper by researchers from Irig and Institut Néel presents a method for creating quantum wells in GaN/AlGaN core-shell structures on GaN for UV emission enhancement.The secret of the structures lies in their very small number of cracks—which behave like non-radiative centers, trapping charge carriers.Because of the difference between the two materials’ mesh parameters, […] >>

Silver nanowires, in the running to replace transparent indium tin oxide electrodes, are plagued by instability under electrical and/or thermal stress.A PhD candidate at LMGP showed that silver nanowires encapsulated in transparent oxides deposited by spatial ALD are stable.Other laboratories and companies also contributed to the project, helping integrate the reinforced silver nanowires into heating […] >>
