| الوصف: | In this study, Green MicroLEDs with different H2 flow during the barrier growth are investigated. We observe that the Indium composition near V-pits affects potential barrier height of the sidewall multiple quantum wells (MQWs) thus has strong impact on screening effect of V-pits. EQE and relative IQE has a dramatically increase with more hydrogen flow during barrier growth, and thermal endurance and wavelength stability was also improved. The enhancement has been confirmed to come from the reduction of non-radiative recombination centers from small V-pits and higher potential barrier height on sidewall MQWs in V-shaped pits which screen dislocations (TDs). These results demonstrate the advantages of modification H2 flow during barrier growth and also provide a new concept to modulate potential barrier height of the sidewall MQWs for better screening effect for further improvement on MicroLEDs performance. |
