![nersc-thumb.jpg This illustration shows what happens in nitride-based LEDs. At left, an electron (negative) and electron hole (positive) recombine and release light (left). In Auger recombination (right) the electron and hole combine with a third carrier, releasing no photon in the process. In this case, the energy loss is also assisted by indirect processes, vibrations in the crystal lattice shown as squiggles.](/-/media/_/images/stories/nersc/nersc-thumb.jpg?h=75&w=135&la=en&hash=FE3EDAFAC071CB5F248882BE61153DA11435532C1269DECB0327F53897A52BA6)
