A group in The Netherlands has achieved a first: injection of spin-polarized electrons in silicon at room temperature. This has previously been observed only at extremely low temperatures, and the achievement brings spintronic devices using silicon as a semiconductor a step closer
Spintronics, or spin electronics, is an emerging field of electronics that aims to be able to represent digital information by using the spin of electrons as well as their charge. When fully developed, spintronic devices could profoundly change data storage devices, computer architecture and so on, and they could reduce energy use to ultra-low levels.
