A study of the effect of fast neutrons and electrons on white and blue LEDs

Current-voltage and light-current characteristics of light-emitting InGaN/GaN heterostructures and blue and white light-emitting diodes before and after irradiation with fast neutrons and electrons are analyzed. A generalized model of a light-emitting heterostructure, with an optically active region...

Zusammenfassung:Current-voltage and light-current characteristics of light-emitting InGaN/GaN heterostructures and blue and white light-emitting diodes before and after irradiation with fast neutrons and electrons are analyzed. A generalized model of a light-emitting heterostructure, with an optically active region with one or several quantum wells in the compensated layer, is suggested. The constants of nonradiative lifetime degradation of blue and white light-emitting diodes under irradiation are estimated.
