Atomic-scale passivation for microLED devices

MicroLED displays face a critical challenge as LED efficiency drops with decreasing chip size. The surface-to-volume ratio increase in smaller LEDs impacts device performance, particularly in III-V compound semiconductors prone to poor-quality oxides when exposed to oxygen. This issue, notably at the mesa sidewall, contributes to diminished light output. Comptek Solutions addresses this using Kontrox, an innovative passivation technology, which transforms III-V surfaces into high-quality crystalline oxides, resolving defects and enhancing surface energy. This novel atomic-level surface engineering technique results in a power-efficient microLED display with improved performance and pixel sizes.
