Size effects of AlGaInP red vertical micro-LEDs on silicon …

To study the size effect of AlGaInP red micro-LEDs on the silicon substrate, we fabricated five AlGaInP red micro-LEDs with different pixel sizes (160 × 160, 80 × 80, 40 × 40, 20 × 20, and 10 × 10 µm 2) and studied their electrical and optical properties.Smaller micro-LEDs have smaller leakage current and larger series resistance and can withstand …
