JILA Quantum Droplet (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption This is an artist's conception of the microscopic "quantum droplet" discovered by JILA physicists in a gallium-arsenide semiconductor excited by an ultra-fast red laser pulse. Each droplet consists of electrons and holes (representing absent electrons) arranged in a liquid-like pattern of rings. The surrounding area is plasma. The discovery adds to understanding of how electrons interact in optoelectronic devices. Credit Baxley/JILA Usage Restrictions Please, use proper credit.
