dc.description.abstract | Electrical and optical characteristics of InGaN-based green micro-light-emitting diodes (mu LEDs) with different active areas are investigated; results are as follows. Reverse and forward leakage currents of mu LED increase as emission area is reduced owing to the non-radiative recombination process at the sidewall defects; this is more prominent in smaller mu LED because of larger surface-to-volume ratio. Leakage currents of mu LEDs deteriorate the carrier injection to light-emitting quantum wells, thereby degrading their external quantum efficiency. Reverse leakage current originate primarily from sidewall edges of the smallest device. Therefore, aggressive suppression of sidewall defects of mu LEDs is essential for low-power and downscaled mu LEDs.
