Spin control for technology

Guiding electrons opens doors for 'new physics,' enables new devices

The wild spins of electrons in a semiconductor can be tamed by guiding their collective motions into a synchronized helix, new research shows. The study, published April 2 in Nature, uncovers new principles of physics and holds promise for the development of new information-carrying gadgets.

“The experiment is a fundamental discovery — a discovery with a device potential,” comments Jaroslav Fabian, of the University of Regensburg in Germany.
