	February 5, 2013 SPIE Photonics West 2013 http://img.optics.org/showdaily/ShowDaily02.pdf, pp 19-23. Uncovering a dark secret: the mystery of LED ³droop² Researchers refine their theories to explain LED droop, a controversial, mysterious malady that threatens the advance of affordable solid-state lighting. Richard Stevenson reports that theorist Chris Van de Walle from the University of California, Santa Barbara supports Auger recombination as the cause of droop.
