俄歇复合对同质结InGaAs探测器探测率的影响
Effect of Auger Recombination on Detectivity of Homojunction InGaAs Detector
【摘要】 通过对InGaAs材料的俄歇(Auger)复合机制的理论分析,给出了少子寿命与材料组分、温度和载流子浓度的关系,从而得到材料参数等对InGaAs探测器的探测率影响的结果,优化材料参数和器件结构可抑制Auger复合机制,提高InGaAs探测器的探测率。
【Abstract】 By theoretical analysis on InGaAs material,lifetime caused by Auger recombination mechanism is calculated depending on the composition,temperature and carrier concentration.The calculated results show that the Auger recombination mechanism is suppressed by optimizing the material parameters and technologic condition,so that high detectivity could be obtained for InGaAs detector.
