Band-to-band Auger recombination in GaInN from first principle calculations — •Markus Heinemann and Christian Heiliger — I. Physikalisches Institut, Justus Liebig University Giessen, D-35392 Giessen, Germany

Recent theoretical work [1] implies that inter-band Auger recombination causes a resonance in the Auger coefficient in the blue to green spectrum and opened a discussion whether this effect may lead to a loss in quantum efficiency of nitrite based light emitters. We investigate the possibility of intra- and inter-band Auger recombination in wurtzite Ga_1−xIn_xN alloys. Using density functional theory and the local density approximation we compute Auger recombination rates for Indium concentrations x ranging from 0 to 100%.
