In 1948, scientists at Bell Labs created something called a transistor, igniting the spark that has created the entire semiconductor industry and all of its progeny. Now, engineers at the University of Delaware hope to place the industry atop another precipice. They have created a technique for controlling a computer's ones and zeros using the spin in silicon electrons (spintronics) when they experience a magnetic field instead of an electric charge. The resulting circuitry will be many times faster than existing solutions and will extend the life of silicon as the primary (and least expensive) semiconductor substrate material.
