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…

AlGaN/AlN Stranski-Krastanov quantum dots for highly efficient electron beam pumped emitters: The role of miniaturization and composition to attain far UV-C emission
Jesus Cañas, Anjali Harikumar, Stephen T. Purcell +6
Conventional ultraviolet (UV) lamps for disinfection emit radiation in the 255-270 nm range, which poses a high risk of causing cancer and cataracts. To address these concerns, sol…
