These characteristics could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times […]

Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs.  The problem is called “efficiency droop” that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents. Efficiency droop, first reported in 1999, has been a key obstacle in the development […]
