For deep ultraviolet light emitting diodes (DUV-LEDs) packaging, the choice of substrate directly affected its performance and reliability. In this paper, a structure was proposed to promote thermal management and lifespan of DUV-LEDs by introducing the ceramic substrate with copper filled thermal hole.

Increase the IQE by Improving the Crystalline Quality for DUV LEDs
2019The roadmap for AlGaN based DUV LEDs is similar to that for InGaN based visible LEDs, such that the success of achieving high crystalline-quality epilayers is the precondition for fabricating high-brightness DUV LEDs. This chapter will review the most adopted technologies for growing high-quality Al-rich AlGaN films, which is regarded as the milestone ...

Screen the Polarization Induced Electric Field Within the MQWs for DUV LEDs
2019This chapter discusses and presents different designs to screen the polarization level in the quantum wells for [0001]-oriented DUV LEDs. By doing so, the quantum confined Stark effect (QCSE) can be decreased. We suggest a simple way to reduce the QCSE by adopting Si-doped quantum barriers.

Enhancing light extraction efficiency of 242 nm DUV micro-LEDs via hybrid nanorod arrays
Optics LettersDeep-ultraviolet (DUV) micro-LEDs are pivotal for applications such as maskless lithography and germicidal disinfection. However, improving light extraction efficiency (LEE) remains a significant challenge. This study presents a novel, to the best of our knowledge, strategy to enhance LEE by employing gold thin-film annealing and dry-etching techniques

On the origin of the enhanced light extraction efficiency of DUV LED by using inclined sidewalls
Optics LettersIt is known that light extraction efficiency (LEE) for AlGaN-based deep ultraviolet (DUV) light-emitting diodes (LEDs) can be enhanced by using an inclined sidewall of mesa. However, the reported optimal inclined angles are different. In this work, to explore the origin for enhancing the LEE of DUV LED by using inclined sidewalls, we investigate the ...
