Researchers found out that the droop in effeciency Nitrade based LEDs experience at the higher power levels, is caused by indirect auger recombination, which is where electrons fall out createing a hole which nearby electrons try to fill in or get knocked out of.
Basically what it means is that at higher levels of power use (such as for household lighting) LEDs receive a drop in effieciancy, nad scientisits knew it happend but never knew why, and now they do. This could mean more effecieint LED lighting could replace incandecent or CFL bulbs.
Neat stuff, a little heady but interesting none-the-less.
