Effect of extended defects on AlGaN QDs for electron-pumped UV-emitters
Jesus Cañas, Névine Rochat, Adeline Grenier +8
We study the origin of bimodal emission in AlGaN/AlN QD superlattices displaying high internal quantum efficiency (around 50%) in the 230-300 nm spectral range. The secondary emiss…
