Monolithically stacked RGB-emission GaInN µLEDs are promising candidates for micro-display applications. However, the degradation of the I-V-L characteristics of blue-emitting GaInN QWs caused by the stacking of upper QWs has been reported. In this study, time-resolved PL measurements were employed to evaluate the crystalline quality of blue-emitting GaInN QWs and to elucidate the mechanism responsible for the I-V-L degradation.
