Abstract
The blue light-emitting diode, arguably the greatest optoelectronic advance of the past 25 years, harbors a dark secret: crank up the current and its efficiencies will plummet. The problem is known as droop, and it´s not only puzzling the brightest minds in the field, it´s also threatening the future of the electric lighting industry.
