基于一种非局域化的输运模型,对不同结构不同温度下的中红外量子级联激光器的输运特性进行了仿真。在这个模型中,利用量子隧穿、微带隧穿以及热载流子输运等长程载流子输运模型,对传统的扩散-漂移方程进行了矫正.并将基于上述集成模型的计算结果和实验结果进行了比较,通过拟合参数的合理设置,计算结果和实验结果得到了很好的吻合. Based on a non-localized transport model, the transport characteristics of the mid-infrared quantum cascade lasers at different temperatures and temperatures are simulated. In this model, the traditional diffusion-drift equation is corrected by using the long-distance carrier transport model such as quantum tunneling, microstrip tunneling and hot carrier transport. Based on the above calculation results of the integrated model Compared with the experimental results, through the reasonable setting of fitting parameters, the calculated results are in good agreement with the experimental results.
