A team of University of California (UC), Santa Barbara researchers has pinpointed a unique defect in the atomic structure of a light-emitting diode (LED) that decreases performance, a finding that could help scientists locate these defects in current LEDs and develop more durable and efficient LED lighting.

"Techniques are available to assess whether such defects are present in the LED materials and they can be used to improve the quality of the material," said Chris Van de Walle, a UC materials professor who oversaw the research.
