Atomic-scale Investigations Solve Key Puzzle of LED Efficiency

From Phys.org - latest science and technology news stories:
From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs -and other solid-state technologies including laser diodes and solar photovoltaics- make them increasingly popular. Their full potential, however, remains untapped, in part because the semiconductor alloys that make these devices work continue to puzzle scientists.
