New nanotransistors keep their cool at high voltages
Power converters play an essential role in electric vehicles and solar panels, for example, but tend to lose a lot of power in the form of heat in the electricity conversion process. Thanks to a new type of transistor developed at EPFL, these converters can perform at substantially improved efficiencies, especially in high-power applications.
Luca Nela was selected for his outstanding thesis, New Technologies to Enhance the Figures-of-Merit of GaN Power Devices, which was supervised by Elison Matioli in the Power and Wide-band-gap Electronics Research lab (POWERlab) in the School of Engineering (STI).
This annual prize, awarded for the first time in 2022, is given to the author of the most outstanding PhD thesis in the field of Microsystems & Microelectronics, and constitutes the EDMI’s highest recognition. The award consists of a certificate and of a CHF 3,000 prize, jointly funded by the Institute of Electrical and Micro Engineering (IEM) and by STI. Congratulations Luca!
The EPFL School of Engineering’s Power and Wide-band-gap Electronics Research Laboratory (POWERlab), headed by professor Elison Matioli, has received the selective 2021 IEEE Transactions on Power Electronics Prize Letter Award, for their paper entitled High-Accuracy Calibration-Free Calorimeter for the Measurement of Low Power Losses authored by Armin Jafari et al. and published on IEEE Transactions on Power Electronics (TPEL). Congratulations Armin and the entire team!
Vanadium oxide is well known to alter its atomic arrangement at high temperatures, and change from insulating to conducting behavior. In this paper, we show that its structure also carries memory, in the form of structural states rather than electronic. These states can be arbitrarily manipulated on short time scales and tracked beyond hours after excitation (exhibiting similar features to glasses). These glass-like functional devices provide a novel scheme for data storage and processing, and could offer a route to neuromorphic computation and multi-level memories. This work has just been published in nature electronics. Congratulations Mohammad and the entire team!
