"defects or impurities—collectively referred to as 'traps'—reduce the efficiency of LEDs and other electronic devices...loss rates orders magnitude greater... energy lost assumed released as phonons, lattice vibrations heating up device, instead of phonons, electron energy transfer to another electron that gets kicked to higher energy state... gallium nitride used in LEDs trap-assisted recombination rates >1 bnX  greater than if using only phonon-mediated process... semiconductor light emitters, any wide-band-gap material"
