UD researchers put 'spin' in silicon, advance new age of electronics

05-18-2007 · EurekAlert!

Electrical engineers from the University of Delaware and Cambridge NanoTech have demonstrated for the first time how the spin properties of electrons in silicon -- the world's most dominant semiconductor, used in electronics ranging from computers to cell phones -- can be measured and controlled.The discovery could dramatically advance the nascent field of spintronics, which focuses on harnessing the magnet-like "spin" property of electrons instead of solely their charge to create exponentially faster, more powerful electronics such as quantum computers.

  3. Low vitamin D levels may be common in otherwise healthy children
    07-09-2007 · EurekAlert!
    Many otherwise healthy children and adolescents have low vitamin D levels, which may put them at risk for bone diseases such as rickets. African American children, children above age nine and with low dietary vitamin D intake were the most likely to have low levels of vitamin D in their blood, according to researchers from the Children's Hospital of Philadelphia.

  5. NRL generates, modulates, and electrically detects pure spin currents in silicon
    12-03-2007 · EurekAlert!
    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.
