QD Researcher Nabs NSF Award

Feb 2009
Matthew Doty, assistant professor in the department of materials science and engineering at the University of Delaware, has received a five-year, $525,000 National Science Foundation (NSF) Faculty Early Career Development Award MatthewDoty.jpgfor his work on quantum dot (QD) molecules, or artificial atoms, which have potential applications in optoelectronic devices such as lasers and sensors, quantum information processing and functional materials.

“Progress towards any of these possible applications requires answers to many fundamental questions about the coupling between quantum dots,” he said. Questions he hopes his research over the next five years will answer include identifying the physical mechanisms of coupling, finding out if particles tunnel between dots or transfer via resonant energy transfer, and discovering the dynamics of interactions between electrons. The career development awards are granted to help young investigators deemed most likely to become the academic leaders of the 21st century launch their independent research careers. Doty joined the UD faculty in 2007 after a three-year stint as a National Research Council research associate at the Naval Research Laboratory. He earned his PhD in physics at the University of California, Santa Barbara.


GLOSSARY
optoelectronics
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
sensor
1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
