Results and Discussion Fig. 6. Simulated relative EQE as functions of current density for conventional LED, LED I, LED II, and LED III. 7
Conclusion • TheSGQB LED with its fifth barrier graded shows improve- ments in both droop behavior and radiative recombination. • The light output power of SGQB LED is enhanced by 7and 42% at 40 and 200 A/cm2, respectively. • the efficiency droop behavior is reduced from 34% inthe conventional LED to 10% in SGQB LED. 8
