The long nanowire (A) is about 110 micrometers long, a shorter nanowire (B) crosses it. The circular section is the metal post from which the nanowires are aligned.

Located in media In a device such as an optical display, positive (purple) and negative (gold) charges are attracted strongly to one another and become trapped (first picture). Because of the unusual rules of quantum physics, the trapped charges can emit light (second picture) if they are spinning in opposite directions. Van Voorhis is creating simulations to show how to selectively create trapped charges in organic light-emitting diode displays to improve efficiency.

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.
