·        Yale University researchers have used terahertz spectroscopy to measure the mobility of electron-hole pairs within cadmium selenide nanoparticles having well-defined sizes ranging from 2.5 nm to 25 nm.  In 2.5 nm nanoparticles, excitons are strongly confined and in 25 nm particles, the excitons are weakly confined.  Photonconductivity scaled with nanoparticle size because, as nanoparticle diameter decreased, electrons and holes travel shorter times before being scattered.  The research was published in “Size dependent photoconductivity in CdSe nanoparticles as measured by time-resoled terahertz spectroscopy”, M. C. Beard, G. M. Turner, and C. A. Schmuttenmaer, Nanoletters, 2(9): 983-987 (August 2002). [ Article in Nature Materials Update (free registration required)]

·        ONR-SBIR/STTR:  Zinc Oxide Based Photonics Devices
Topic N03-113  TECHNOLOGY AREAS: Sensors, Electronics, Battlespace
ACQUISITION PROGRAM: ACTIII AAR-47 Missile Warning Systems
Full Text: http://www.acq.osd.mil/sadbu/sbir/solicitations/sbir031/navy031.htm.
Deadlines:  DoD will begin accepting proposals on December 2, 2002.   This solicitation closes on January 15, 2003 at 5:00pm EST.
OBJECTIVE: To develop zinc oxide technology for commercial UV - visible light emitting diode (LED) and laser diode (LD) applications. Other major application areas include sensors and high frequency communication devices. This technology will include diode laser design and fabrication.
DESCRIPTION: High brightness, long lifetime light emitting diodes and lasers for the blue/visible and blue/UV regions of the spectrum are desirable for use as light sources and as sensors. Semiconductor light sources and lasers are desirable because they are lightweight and can use battery sources, increasing portability. The choice of semiconductor sources in the blue wavelength range is limited to gallium nitride heterostructural devices as a light emitting diode. No commercially available laser diode sources have been developed. Zinc oxide is a wide bandgap material (3.3 eV) with structural and electrical characteristics similar to those of gallium nitride. Interest in use of zinc oxide for devices is increasing rapidly due to breakthroughs in p-type doping. Zinc oxide has been grown with p-type carrier concentrations in the range of 1015 to 1018 per cm3. Compared with gallium nitride, results for zinc oxide show higher doping levels, markedly higher activation of dopant atoms, better electron and hole mobilities, and decreased defect densities. Possibilities exist for fabrication of zinc oxide homoepitaxial devices that may show greater thermal stability, higher powers and longer lifetimes than would heterostructural designs. This program is devoted to developing zinc oxide technology for system integration and analyzing the overall performance for practical applications. . A laser with average power of 10 mW or greater would be desirable.  CONTACTS:  Yoon-Soo Park, Ph.D., Phone: 703-696-5755, Fax: 703-696-2611, Email: parky@onr.navy.mil; Dr. Jerry Meyer (Code 561), Phone: 202-757-3276 Fax: 202-404-8613, Email: meyer@sisphus.nrl.navy.mil




E.    Overview Articles


·        The adoption of green LED traffic signals by municipalities was covered in a feature article on the website for the Consortium for Energy Efficiency.  The article covered some of the technological challenges that had to be overcome before efficient, long-lasting LEDs could be developed and packaged so that existing signals could be retrofitted with LED lamps.  A significant hurdle to adoption of the new technology is the in initial cost, with green LED lamps running 80 to 100 times more than traditional, incandescent bulbs.  However, savings due to LEDs’ lower operating wattage and much longer lifetime more than make up for the high initial costs.  In addition, because of the extremely low wattage requirements of LED traffic signals, they can be powered by photovoltaic systems.  Such systems are becoming commonplace as backups during power failures. [ Article in Epri Journal Online]

·        A recent article in Laser Focus World has provided an overview of the current state of solid-state illumination technology.  The article provides an overview of LED technology generally, and also the technologies used to generate white light using LEDs.  Challenges in the use of phosphors in creating white light are also discussed. [ Article in Laser Focus World]

·        The Office of Naval Research has published a history of GaN blue LEDs on its Roadmap website.  The article “A Brief History of GaN Blue Light-Emitting Diodes”, authored by Herbert Paul Maruska, can be reached by clicking on materials, then on GaN.  The ONR website requires free registration.  [ Article in CompoundSemi News ]

·        The Economist ran an article focused on LED technology in its October 3, 2002 edition.  The article called LED technology a “solid future for lighting”.  The article reviewed the three basic methods for producing white light with LEDs, and mentioned Nichia, Lumileds, GELcore, Osram and Color Kinetics by name.  It also touched on Japan’s Light for the 21st Century Initiative and the Next Generation Lighting Initiative in the yet-to-be-passed energy bill in the US Congress.

·        LEDs were the topic of a Living On Earth radio broadcast on NPR stations on November 1, 2002.  The broadcast was in two segments.  The first segment provided an overview of the history of lighting and of LED technology.  This segment contained quotes from Sandia’s Jerry Simmons, Color Kinetics’ Kevin Dowling, and IEEE Spectrum’s Glenn Zorpette.  The second segment profiled Light Up the World Foundation’s Director, David Irvine-Halliday, and his foundation’s efforts to bring white LED lighting to the developing world.  [ Transcript]
