Abstract:The photosensitive and electrical characteristics of almost e ciency-droop-free UV-C LEDs with a Mgdoped LQB and Si-doped shallow periodic electron injection layer in between Mg-doped EBL and Hole injection layer are studied numerically in order to enhance the optical and electrical performance.SiLENSe software is used to look into the QB-QWs region's IQE, energy band pro les, electron and hole concentration, and radiative recombination rates. The ndings show that the proposed UV-C LED has peak IQE 140% higher… 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.
