Abstract: A high and efficient green light (550 nm) LED’s design and performance characteristics were studied in this work. Using Vegard’s law, the calculated mole fraction was found to be In0.28Ga0.72N. The lattice parameter was investigated and amount of strain involved in the structure was also calculated alongside a lattice matched structure. For zero strain the critical thickness of the structure was also determined. Some electrical and optical properties were investigated like Internal Quantum Efficiency (IQE), External Quantum Efficiency (EQE) and Optical output Power. Each parameter were observed against the change in Current density. The effect of Shockley read Hall parameter was also investigated for achieving high Internal Quantum Efficiency, External Quantum Efficiency and output power as well.
