Nonpolar Green LEDs Based on InGaN
Current green LEDs suffer from lower efficiency compared to blue and red LEDs. This lower efficiency hampers the use of RGB solutions to solid state light sources. This project will bridge the ¿green gap¿ by developing nonpolar green InGaN-based LEDs with state of the art properties. These properties include record low defect density, InGaN emitters, high hole concentration, and p-type InGaN, all incorporated in nonpolar orientations. Commercial Applications and other Benefits as described by the awardee: The successful development of this LED technology will provide a low cost, very-high-efficiency green LED for all solid state lighting applications, including general illumination. The increase in efficiency of the green LED will enable RGB systems to exceed LED metrics of 150 lumens per watt.
