Abstract :
Chemically vapour deposited phosphosilicate glass films were used to getter epitaxial gallium-phosphide layers. Significant improvements in the electroluminescent efficiency of yellow light-emitting diodes fabricated from the gettered material were observed. Results suggest that the gettering removes compensating impurities as well defects which influence minority carrier lifetime.
