Phenomenological Model of Radiation Hardness of LEDs Based on AlGaInP Heterostructures with Multiple Quantum Wells

Autor: Anastasiia V. Simonova, A. V. Gradoboev, K. N. Orlova

Publikováno v: Materials Science Forum. 970:167-176

Neutron degradation of LEDs based upon AlGaInP heterostructures (λ=630 nm and λ=590 nm) with multiple quantum wells are presented in the article. For the initial red LED (λ=630 nm) we can clearly distinguish three characteristic regions. In the sm
