Reflective Metal/Semiconductor Tunnel Junctions for Hole Injection in AlGaN UV LEDs
Yuewei Zhang, Sriram Krishnamoorthy, Fatih Akyol +6
In this work, we investigate the use of nanoscale polarization engineering to achieve efficient hole injection from metals to ultra-wide band gap AlGaN, and we show that UV-reflect…

Tunnel-injected sub-260 nm ultraviolet light emitting diodes
Yuewei Zhang, Sriram Krishnamoorthy, Fatih Akyol +5
We report on tunnel-injected deep ultraviolet light emitting diodes (UV LEDs) configured with a polarization engineered Al0.75Ga0.25N/ In0.2Ga0.8N tunnel junction structure. Tunnel…
