Abstract:In this study, a new design of quantum barriers has been investigated numerically with the purpose of improving the optical performance of blue InGaN light-emitting diodes (LEDs). Through analysis of energy band diagrams, carrier concentrations, carrier current densities, Auger recombination rates, and radiative recombination rates, we obtain simulation results showing that the proposed structure with a mix of AlGaN and InGaN quantum barriers can significantly improve the light output power and internal quantu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
