The aeronautics and automotive industries are looking for more compact, efficient power converters. Leti’s latest research on a converter built on gallium-nitride-on-silicon components is producing some results sure to please these demanding industries. When tested on a demonstrator system, the converters displayed low losses and high switching speeds enabling frequencies up to 30 MHz. The […] >>

A joint INAC-CNRS-Thales research team achieved record intensity- and sign-tunable spin-charge conversion in the two-dimensional electron gas at the interface between a layer of strontium titanate and another layer of lanthanum aluminate. The conversion rate was five to ten times higher than with the materials currently used. The researchers worked at 7 K, injecting a […] >>

MEMS radio-frequency micro-switches developed by Leti could be chosen by the European Space Agency for tomorrow’s space applications. While it is still too early to tell, Leti is doing everything it can to increase its chances of success! First, Leti researchers have integrated the switches into a collective thin-layer packaging—a key advantage over individually packaged […] >>

Satellite operators are actively seeking to determine which type of waves they should focus on to secure a slice of the future 5G market. Research conducted by France’s national space agency CNES at Leti set out to answer this question. The study is assessing four potential types of waves: OFDM, EW-OFDM, PS-OFDM, and FBMC. The […] >>

Over the past several years, the application of mechanical constraints to semiconducting quantum dots has been broadly used to fine-tune the dots’ emission wavelength to create single-photon sources, for example. Researchers at INAC integrated several InAs quantum dots into a GaAs nanowire coated with an amorphous silicon shell to create quantum dots deformed along their […] >>
