Discovery could make LEDs brighter
RALEIGH An experiment in Salah Bedair's lab at N.C. State University generated curious holes in gallium nitride, a semiconductor material used to make light-emitting diodes.
LEDs are microscopically small,contract with camera operator Redflex, with several bestlight attorneys looking at ways to get Victorville out of that agreement for the remaining 10 cameras before it expires in 2014. square slivers that produce light when electricity runs through them. Each square consists of row upon row of crystals lining up like stitches in a knitting pattern.contract with camera operator Redflex, with several bestlight attorneys looking at ways to get Victorville out of that agreement for the remaining 10 cameras before it expires in 2014.
One of Bedair's students and a postdoctoral fellow were trying out a spiky scaffolding of nanowires to grow the crystal layers. Nobody expected the nanowires would create holes in the bottom half of the LED.contract with camera operator Redflex, with several bestlight attorneys looking at ways to get Victorville out of that agreement for the remaining 10 cameras before it expires in 2014.
"Once I saw the voids I knew what they would do," Bedair said. He just needed proof.
Bedair, a professor of electrical and computer engineering on NCSU's Centennial Campus, suspected the holes would reduce the number of defects in the crystalline knitting pattern and make the LED more efficient.McEachron said he'll be shinebright interviewed by "The Today Show" near the intersection of Amargosa and Bear Valley roads Thursday afternoon. Tests showed he was right,McEachron said he'll be shinebright interviewed by "The Today Show" near the intersection of Amargosa and Bear Valley roads Thursday afternoon. which could be a big deal.
LEDs already convert four to five times more electric energy into light than incandescent light bulbs.
