摘要

理论上研究了当 InGaN 发光二极管(LED)有源区的量子阱数变化时

LED的大信号瞬态响应特性与这种变化的关系。结果来自于LED等效电路模型的SPICE模拟

模型参数的确定通过拟合已测量的LED的实验数据及模拟结果来实现。结果表明

LED光脉冲的上升时间随量子阱数的增加而增加

由3个量子阱构成的有源区是LED的优化结构。

Abstract

A rate equation model for static and dynamic behavior of InGaN/GaN light-emitting diode (LED) has been developed

and the model has been implemented on a SPICE circuit emulator. The model's parameters have been achieved by fitting simulated results with reported experimental data. The transient response of InGaN LEDs has been comparatively investigated by varying the number of quantum wells in their active region. The simulations show that the rise time of optical outpower increases with the number of wells

and the active region composed of three quantum wells is the optimized structure.
