A team of researchers has discovered a way to cool electrons to a temperature of 228 degrees Celsius below zero without using bulky cooling systems.
To achieve this, these experts, coordinated by Seong Jin Koh, a professor in the Department of Engineering and Materials Science at the University of Texas at Arlington, have designed a chip equipped with a set of nanostructures that force these particles to pass through a quantum well. .
In the study, published in the journal Nature Communications , the scientists point out that in this way they have been able to suppress the thermal excitation that electrons experience at room temperature , a phenomenon that normally occurs in nature.
"Although other groups had already managed to reduce the temperature of the electrons before, ours is the first to do so without using baths of extremely cold cooling products, such as liquid nitrogen or liquid helium," says Seong Jin Koh.
The advance, according to experts, could allow the design of electronic devices whose energy consumption was ten times less than the current ones.
