2014-04-04 15:51:32

Brett Smith for redOrbit.com - Your Universe Online At low power, commonly used LEDs are very efficient. However, when these same LEDs receive enough power to light a room, they lose a significant amount of efficiency, a term referred to as the “green gap” because the efficiency loss is most pronounced with green LEDs. According to a new online report published in Nano Letters, two engineers from the University of Michigan have modeled nanostructures with less width than a DNA...
