Investigating efficiency droop in InGaN/GaN quantum well structures using ultrafast time-resolved terahertz and photoluminescence spectroscopy

| Description | Understanding the physical mechanism(s) responsible for efficiency droop in InGaN/GaN quantum well light-emitting diodes (LEDs) is critical in developing strategies to mitigate its effect and enable the wide-spread adoption of GaN-based LEDs in the illumination market. We have discovered that the saturation of localised hole states may be playing a part in the onset of efficiency droop. |
| Exploitation Route | Development of strategies to mitigate the droop in LED efficiency. |
