Experimental and Theoretical Analysis on GaN Multiple Quantum Well Blue LED

Li Weijun(National Center of Supervision&Inspection on Electric Light Source Quality(Shanghai),China National Lighting Fitting Quality Supervision Testing Center(CLTC),Shanghai Alpha Lighting Equipment Testing Ltd.(SALT),Shanghai 200233)  
A 2D simulation of electrical luminescence spectrum of InGaN/GaN multiple quantum well(MQW) blue LED by APSYS software with a dot-well model is investigated.It is found that electrical luminescence simulation results based on the quantum dot model are in agreement with the experimental data,which suggests that the In-rich quantum dots(QDs) due to the spatial inhomogeneity of the indium composition plays a very important factor of the emission mechanics of InGaN/GaN.At the same time,optical characteristics of polarization matching InGaN/AlGaInN multiple quantum are also discussed using the dot model for the first time.
【Key Words】: InGaN/GaN LED recombination rate quantum dot model polarization match
