NRL generates, modulates, and electrically detects pure spin currents in silicon

NRL scientists have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. This demonstration is a key enabling step for developing devices which rely on electron spin rather than electron charge, an emergent field known as "semiconductor spintronics." Progress in this field is expected to lead to devices which provide higher performance with lower power consumption and heat dissipation.

1. NRL scientists demonstrate efficient electrical spin injection into silicon
   07-16-2007 · EurekAlert!
   NRL scientists have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. This demonstration is a key enabling step for developing devices which rely on electron spin rather than electron charge, a field known as semiconductor spintronics, and is expected to provide higher performance with lower power consumption and heat dissipation.

3. UD researchers race ahead with latest spintronics achievement
   10-26-2007 · EurekAlert!
   In a rapid follow-up to their achievement as the first to demonstrate how an electron's spin can be electrically injected, controlled and detected in silicon, electrical engineers from the University of Delaware and Cambridge NanoTech now show that this quantum property can be transported a marathon distance in the world of microelectronics -- through an entire silicon wafer. The finding confirms that silicon -- the workhorse material of present-day electronics -- now can be harnessed up for new-age spintronics applications.

4. New field-deployable biosensor detects avian influenza virus in minutes instead of days
   09-27-2007 · EurekAlert!
   Quick identification of avian influenza infection in poultry is critical to controlling outbreaks, but current detection methods can require several days to produce results. A new biosensor developed at the Georgia Tech Research Institute can detect avian influenza in just minutes. In addition to being a rapid test, the biosensor is economical, field-deployable, sensitive to different viral strains and requires no labels or reagents.
