Abstract :
Under high carrier and optical excitation (1019 cm-3), II-VI and As, P-based III-V light-emitting structures exhibit a slow degradation due to recombination-enhanced defect reactions. The authors have found, using II-VI laser structures, that this degradation can be partially recovered with excitation at low carrier densities (5×1016 cm-3)
