We present the simulation and fabrication with characterization of InGaN MQWs based green LEDs on c-plane sapphire substrate in this paper. The simulated results show that internal quantum efficiency droop has improved from 13% in reference structure to 4% in the modified structure at 200 A/cm 2 current density with replacement of the 15 nm AlGaN step index EBL with a super-lattice pair of graded AlGaN EBL following a reduction in droop, polarization charges and increment in hole injection towards active region.
