JILA physicists see the once-hidden electronic behavior of semiconductors. The computer plots show how energy intensity (ranging from low in blue to high in red) varies as electronic structures called excitons absorb laser light and emit energy at various frequencies. The pair of similar "butterflies" indicates that an exciton is absorbing and emitting energy in a predictable pattern.

Sands (left),director of Purdue's Birck Nanotechnology Center in Discovery Park, and a graduate student operate a "reactor" in work, which deposits gallium nitride on silicon at temperatures of about 1,000 degrees Celsius. Located in media Organic phosphors developed at the University of Michigan could one day lead to cheaper organic light-emitting diodes. Here, they glow in blue and orange when triggered by ultraviolet light.
