#Laser allows solid-state refrigeration of a semiconductor material
“#Laser allows solid-state refrigeration of a semiconductor material” University of Washington researchers used an infrared laser to cool a solid semiconductor material—labeled here as “cantilever”—by at least 20 degrees C, or 36 F, below room temperature.
