Turning Quantum Dots Into Spintronic Transistors

Abstract:
Spintronics is one of the technologies that is set to change the nature of computing and communications in the next few years. Until now, all electronic components such as transistors have exploited a single property of the electron: its charge. But electrons have another property, their spin, which can also be exploited to encode information.

So finding ways to manipulate electron spin is a priority in many labs around the world. And today, many spin-based devices are close to commercialization. That's not to say there isn't room for more and today E. C. Siqueira and Guillermo Cabrera at UNICAMP in Brazil put forward a new idea for a spintronic transistor based on the exotic phenomenon of Andreev reflection.
