Abstract
- The AlGaN-based deep ultraviolet (DUV) light-emitting diodes (LEDs) with p-hBN layer are investigated numerically. In comparison with the conventional AlGaN DUV LEDs, the proposed LED can significantly improve the carrier injection, radiative efficiency, as well as the electroluminescence (EL) intensity under the same applied forward bias. Simultaneously, the light extraction efficiency in the LED using p-hBN instead of p-AlGaN exhibits a more than 250% increase at the applied voltage of 7.5 V due to the smaller loss of reflection and absorption of the emitted light.
