What if IoT antennas could be made even smaller without compromising efficiency simply by tuning their frequency? A PhD candidate at Leti did just that! She also developed an analytical model that is as reliable as today’s simulators. Leti fabricated an antenna whose size is no more than 1/15th of the wavelength, compared to the […] >>

The Flash Arise project, funded by France’s national research agency (ANR), was set up to develop a solution for detecting SARS-Cov-2 droplets or aerosol in the air within a maximum of 30 minutes. Leti and the Institut Pasteur are engaged in the project, which kicked off in March. The partners’ hope to be able to […] >>

Researchers from Irig, Institut Néel, and EPFL in Lausanne developed a sustainable electrode for the production of hydrogen by photoelectrolysis, a CO2-free process. This photosynthesis-inspired innovation uses non-toxic and abundantly-available materials, and features a p-type semiconductor interface that absorbs light with a molecular catalyst. The semiconductor material, a copper iron oxide, is covered with a […] >>

Leti is developing a ferroelectric tunnel junction for the EU Beferrosynaptic project, which kicked off in early 2020. The junction could become the core component of tomorrow’s neuromorphic processors. Neuromorphic processors or chips differ from conventional chips in that memory and computing resources are very tightly integrated, just like in the human brain. Plus, they […] >>

Hybrid perovskite photovoltaic cells can deliver yields of more than 20%. However, they do not age well. Researchers from Irig and INES joined forces to investigate the mechanisms that underpin the formation of the best-known hybrid perovskite, MAPbI3*, which is synthesized in thin layers. The research revealed two things that explain the behavior of cells […] >>
