p-n结结深对台面型 InSb 光伏型探测器性能的影响

摘要

Based on Silvaco 2D numerical simulation, the effects of p-n junction depth on the crosstalk and quantum efficiency of the mesa InSb photovoltaic detector are studied.The correlation be-tween the longitudinal electric field distribution, the transverse electric field distribution, as well as the recombination rate of detector and the p-n junction depth are analyzed.The results show that the p-n junction depth has a profound effect on the inherent physical mechanisms of the crosstalk and the quantum efficiency.And it is of great importance to the optimization of the mesa InSb photovoltaic detector.%基于Silvaco二维数值仿真研究了p-n结结深对台面型InSb光伏型探测器串音和量子效率的影响,通过分析探测器中横向电场分布、 纵向电场分布、 复合速率分布等与p-n结结深的相关性,揭示了p-n结结深影响探测器的串音和量子效率的内在物理机制, 并获得了对探测器优化设计有指导意义的研究结论.
