Micro light-emitting diodes (µLEDs), crucial for advanced displays and communication systems, face efficiency challenges due to sidewall defects. This study investigates the impact of various passivation layers, including SiO 2 , Al O 3 HfO on AlGaInP-based 620 nm red µLEDs. We fabricated devices with two mesa sizes demonstrated that atomic layer deposition (ALD) passivation, especially significantly enhances performance. shows improvement in external quantum (EQE) by up 57.9% a 13 × 20 µm...
