Crowell comments on spin Injection breakthrough

                                                       

In a recent interview with Science Magazine, Professor Paul Crowell comments on the potential significance of a recent experiment done at the University of Twente in Enschede, Netherlands that successfully managed to control the polarization of spining electrons in silicon at room temperature .

Previously, so-called "spin injection" had only been achieved in exotic materials such as gallium arsenide and indium arsenide or in silicon at temperatures below 150 degrees Kelvin. The breakthrough was reported in an article in the Journal Nature in late November.

Crowell called the experiment a "compelling demonstration" but cautioned that the larger goals of Spintronics such as very low energy computing are still years away.
