Spintronic thermoelectric power generators: A step towards energy efficient electronic devices

(Phys.org) --Imagine a computer so efficient that it can recycle its own waste heat to produce electricity. While such an idea may seem far-fetched today, significant progress has already been made to realize these devices. Researchers at the Nanostructured Materials Research Laboratory at the University of Utah have fabricated spintronics-based thin film devices which do just that, i.e. convert even minute waste heat into useful electricity.
