Silicon Spin Transistors (IMAGE) University of Utah Caption Left, a dozen three-contact nickel-iron transistors sit on a silicon chip coated with an ultra-thin film of magnesium oxide. Right, a six-transistor chip attached to electrical contacts for experiments showing that the magnetic "spins" of electrons can be aligned as they travel through silicon at room temperature -- a step toward "spintronic" computers and other devices that are faster and more energy efficient than their electronic counterparts.
