Investigation and modeling of the role of interface defects in the optical degradation of InGaN/GaN LEDs

Nicolas Grandjean, Jean-François Carlin, Camille Haller

We investigate the degradation mechanisms of In0.2Ga0.8N/GaN light emitting diodes through combined experimental analysis and simulations. The devices were submitted to constant current stress at 100 mA. Depending on the measuring current level, two degrad ...
