Influence of Size Reduction and Current Density on the Optoelectrical Properties of Green III-Nitride Micro-LEDs

We have investigated the effect of chip size on the forward voltage, light output, emission image and spectral shift of InGaN based green LEDs (518 nm) as a function of current density. The size of the chips was varied from 10 to 100 µm. The smaller chips exhibited higher light output power a...
