Researchers at UT Arlington have created the first electronic device that can cool electrons to -228 degrees Celsius (-375F), without any kind of external cooling. The chip itself remains at room temperature, while a quantum well within the device cools the electrons down cryogenic temperatures. These cryogenic, quantum well-cooled electrons could allow for the creation of electronic devices that consume 10 times less energy than current devices, according to the researchers.
