Description
Summary:We propose a simplified method to improve the efficiency of deep ultraviolet (DUV) LEDs by incorporating a micro ring-structured cavity subsequently enhancing the light extraction efficiency. Amazingly, our design exhibits an impressive 25% higher light output power compared to conventional-LEDs, at current of 120 A/cm 2 .
