摘要
基于有限差分方法对金属半导体金属(MSM)光探测器进行了二维分析,得到有明确物理意义的模拟曲线和结论,并结合模拟结果对MSM光探测器的光电直流特性进行了分析.全部模拟工作都是基于半导体物理的基本微分方程完成的,这对于未来优化设计探测器的性能和结构有很大的意义.
A 2D finite-difference method is developed to study a metal-semiconductor-metal photodetector(MSM-PD).The numerical simulation is based on the Poisson equation and continuity equations for electrons and holes.The distributions of the electrical field,the carriers and the current density in the MSM-PD are calculated,and the DC characteristics of the photodetector are analyzed.
