Exploring swift-heavy ion irradiation of InGaN/GaN multiple quantum wells for green-emitters: the use of Raman and photoluminescence to assess the irradiation effects on the optical and structural properties

International audienceXe SHI irradiation of InGaN/GaN MQWs leads to surface damage and intermixing at the interfaces. The introduced defects cause a strong quenching of the luminescence as well as a change in the excitation mechanisms
