Silicon-based 'spintronics' device developed
A development that could advance of the hottest areas of physics research - "spintronics" - has been announced by US scientists.
Ultimately, physicists hope that research in spintronics could lead to smaller, faster and less power hungry computers. These machines would operate using logic devices based on manipulating and measuring the spin of electrons, rather than turning current on and off.
Now researchers have for the first time shown that they can inject spin-polarized electrons into silicon, manipulate them, and measure them coming out the other side.
