On the origin of the enhanced light extraction efficiency of DUV LED by using inclined sidewalls.

Optics Letters
It 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.
