Interpaly of extended defect, point defects, and localization on InGaN LED EQE droop

What is it about?

Spatially resolved study of EQE droop in InGaN LEDs, allowing unambiguous comparison of different characteristic types of droop on the same device.

Why is it important?

LED efficiency droop is mostly an extrinsic effect (e.g., defects) rather than intrinsic (e.g., Auger).
