Abstract
Effect of number of wells with different thicknesses of P layer on Internal Quantum Efficiency(IQE), I–V relationship, Power current, and spontaneous rate of blue InGaN/GaN multiple quantum well (MQW) light-emitting diodes (LEDs) is simulated and investigated with the help of APSYS software. Result reveals that LED with single Quantum well and thin P type Electron Blocking Layer (EBL) gives significantly good result for low injection level. For high injection level thick EBL and multiple Quantum well gives better result. At low injection level LED with single Quantum well shows IQE around 98.20 %.
