The effects of electron beam and γ-ray irradiation on the optical properties of InGaAs/GaAs quantum dot (QD), quantum well (QW), and bulk structures, which were grown by metal organic vapor phase epitaxy, have been investigated. Optical properties of all the structures were degraded by both kinds of irradiation. Electron beam irradiation caused a larger reduction in the photoluminescence (PL) intensity...
