Impact of Sidewall Conditions on Internal Quantum Efficiency and Light Extraction Efficiency of Micro‐LEDs (Advanced Optical Materials 10/2023)

Highly-bright, highly-efficient, and ultra-small micro-light emitting diodes (μLEDs) are necessary for realizing next-generation displays. Jeong-Hwan Park and co-workers report how the sidewall conditions of the μLEDs determine the device performance. As presented in article number 2203128, the small area at the sidewall of μLEDs changes the performance of μLEDs including internal quantum efficiency and light extraction efficiency.
