Semiconductors, selective behavior, experimental data, image 1

Physicists at JILA have confirmed subtle collective behavior among electronic structures in semiconductors, research that may help improve the design of optoelectronic devices.

In this first image of three (showing new experimental data), matching large peaks in the foreground, showing energy intensity ranging from low in blue to high in red, indicate that pairs of large electronic particles called excitons are oscillating in concert as they absorb ultrafast laser light and emit energy at various frequencies.
