Kill carbon in UV-emitting LEDs to make better pathogen killers

By Eileen De Guire / May 15, 2012

The efficiency of LED devices is limited by carbon point defects in the aluminum nitride transparency layer, which absorb useful wavelengths of light (around 4.7 eV). North Carolina State University researchers used computational methods and detailed experiments to make the discovery. Credit: Doug Irving; NC State. The Materials Genome Initiative is shining the spotlight on…
