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.
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!
