US invests $6.4million in LED development

The funding includes $4,6m from the American Recovery and Reinvestment Act. The projects selected are expected by the DOE to fill key technology gaps in both LED and OLED technologies. It stated that the funding is part of a scheme to accelerate progress toward creating a US led market for high efficiency solid state lighting sources. The funding is broken down as follows: National Renewable Energy Laboratory, Colorado: NREL will seek to demonstrate the viability of high bandgap gallium indium phosphide alloys for synthesis of inexpensive, efficient green LED devices. NREL will receive $1.8m in funding from the American Recovery and Reinvestment Act. Pacific Northwest National Laboratory, Richland, Washington: PNNL seeks to develop new, stable materials for high efficiency blue OLEDs. PNNL will receive $1.0m in funding from the American Recovery and Reinvestment Act. Sandia National Laboratories, Albuquerque, New Mexico: SNL seeks to improve the efficiency of green LEDs by growing on gallium nitride substrates. Sandia will receive $1.8m in funding from the American Recovery and Reinvestment Act. U.S. ARMY Research Laboratory, Adelphi, Maryland: ARL seeks to exploit the negative polarisation charge at the active region to achieve efficient green LEDs. ARL will receive $1.8m from appropriated program funds.
