Light extraction from LED structures is a major challenge in the development of quaternary (Al 1 − xGa x) 0.5 In 0.5 P-based light-emitting diodes (LEDs) owing to its being limited by substrate absorption and total internal reflection. One approach for improving light extraction is to minimize total internal reflection by inserting a middle-refractive-index material between the …
