Simulation of InGaN/GaN multiple quantum well light-emitting diodes with Quantum Dot electrical and optical effects

We report on the 2D simulations of electrical and optical characteristics for green color InGaN/GaN multiple quantum well light-emitting diodes by the APSYS software. The In-rich quantum dot-like structure in InGaN/GaN multiple quantum wells has been considered with quantum dot model. The simulation results are in good agreement with experiment and indicate that quantum dot spontaneous emission and non-equilibrium quantum transport play an important role in the InGaN/GaN multiple quantum well light-emitting diodes
