Development of DUV-LED grown on high-temperature annealed AlN template

Gallium Nitride Materials and Devices XVI, 2021
A combination of the sputtering deposition and high-temperature annealing is a promising technique for preparing low-dislocation-density AlN templates. In this talk, MOVPE growth behavior of AlGaN films grown on the annealed AlN templates and on conventional MOVPE-grown AlN templates was comprehensively discussed.

Current induced degradation study on state of the art DUV LEDs

Microelectronics Reliability, 2018
Abstract We present the first comprehensive study of the degradation of 16 mW state of the art UVC LEDs emitting at 280 nm. The study, based on combined electrical and spectral characterization, allows to identify different degradation regimes and mechanisms, and to formulate hypotheses on their origin.

High photoluminescence intensity of heterostructure AlGaN-based DUV-LED through uniform carrier distribution

Physica Scripta, 2023
We report a numerical analysis of the variation of Aluminium (Al) composition in Al Gallium Nitride (AlGaN)-based Deep-Ultraviolet Light-Emitting Diode (DUV-LED) and its effects on the carrier concentration, radiative recombination, and photoluminescence
