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…
Internal quantum efficiency of AlGaN/AlN quantum dot superlattices for electron-pumped ultraviolet sources
A. Harikumar, F. Donatini, C. Bougerol +6
In this paper, we describe the growth and characterization of 530-nm-thick superlattices (100 periods) of AlxGa1-xN/AlN (x = 0, 0.1) Stranski-Krastanov quantum dots for application…
Assessment of AlGaN/AlN superlattices on GaN nanowires as active region of electron-pumped ultraviolet sources
I. Dimkou, A. Harikumar, F. Donatini +9
In this paper, we describe the design and characterization of 400-nm-long (88 periods) AlxGa1-xN/AlN (0 < x < 0.1) quantum dot superlattices deposited on self-assembled GaN nanowir…
