Abstract:
Because the polarization effect influences the distribution of the carriers in the multiple quantum wells of the light-emitting diodes (LEDs),the light-emitting efficiency is also affected. The influence of the polarization effect on GaN-based LEDs' performance is simulated. By simulating four different types of electrode shapes,it's found that the electrode shape influences not only the photoelectric characteristics but also the optical absorption by the semiconductor. Through the optimization of the elect...
