This news release from the University of Utah discusses the physics department's discovery of "a new generation of faster, cheaper computers and electronics by building the first 'organic spin valves.'" The physicists, who recently published their findings in _Nature_, developed semiconductors made of organic material that operate similar to switch valves to direct the flow of electrical current. The website educates users about spintronics and spin valves and their relationship to semiconductors. Visitors can learn how the new invention can be applied to computer memory chips and air pollution, magnetic fields, radiation, and light sensors.
