What is it about?
UV light emitters holds great promise for many applications line water purification, clean and contaminants-free disinfection, dense data storage etc. This article includes a in-depth literature review on deep UV optoelectronics and on focus on the enhancement of the efficiency of UV LEDs.

Why is it important?
There has been a significant interest in replacing environmentally hazardous mercury based UV lamps for sometime now; however, the poor efficiency of UV LEDs is preventing us in doing so. Hence, the enhancement of the efficiency is imminent. In this article, we report a nanophotonic technique ( use of the GaN qunatum disks) in a established (III-Nitride) material system to enhance the efficiency of UV LEDs.
Perspectives
Working in this research project was a pleasure as it has co-authors with diverse expertise make the collaboration very productive. As this article is specifically focused on the material growth and characterization, with the very promising result our next step is to develop an efficient LED device structure.
