Analysis of Size-Dependent Quantum Efficiency in AlGaInP Micro–Light-Emitting Diodes With Consideration for Current Leakage

This study fabricated and analyzed AlGaInP-based red micro–light-emitting diodes (LEDs) ranging from 2 to 15 μm in size. To collect photons from a single micro-LED at this scale, a solar cell chip near the micro-LEDs was used. Quantum efficiency decreased at a faster rate than...
