Cathodoluminescence as an Effective Probe of Carrier Transport and Deep Level Defects in Droop-Mitigating InGaN/GaN Quantum Well Heterostructures
Zhibo Zhao, Akshay Singh, Jordan Chesin +7
Commercial InGaN/GaN light emitting diode heterostructures continue to suffer from efficiency droop at high current densities. Droop mitigation strategies target Auger recombinatio…
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…
