Enhancing the performance of high-power DUV-LEDs with sloped sidewall by introducing N-electrode holes and interrupted mesa.

Optics Express
This study introduces innovative structural enhancements in deep ultraviolet LEDs (DUV-LEDs) to optimize Performance. By implementing a 46.9° sloped mesa sidewall, we have designed what we believe to be two novel structures: an n-electrode hole structure

Performance enhancement of 254 nm DUV LEDs utilizing tunnel junction contact layer and asymmetric polarization-induced doping electron blocking layer.

Optics Express
Deep ultraviolet light-emitting diodes (DUV LEDs) operating at 254 nm face significant challenges in achieving efficient hole injection, resulting from the low p-type doping efficiency of high-Al-content AlGaN and the consumption of holes caused by ...
