摘要
较强功率的激光辐照半导体探测器时既产生光电效应又产生热效应,提出了反映光电效应的载流子输运模型和反映热效应的热扩散模型.计算了不同激光辐照功率密度下PC型HgCdTe探测器内的光生载流子浓度和热平衡载流子浓度,由此对探测器的瞬变行为进行了仿真计算,仿真结果与实验结果相吻合.
Abstract
Photoconductive effect and heat effect in semiconductor photoconductive detectors when they are irradiated by laser were considered simultaneously. A transportation model of photoconductive carriers and heat transmission model were established. The photoconductive carriers consistency and the heat equilibrium carriers consistency in PC-type HgCdTe detectors under various laser irradiation density were calculated. Instantaneous change behaviors of the detectors were imitated further. The imitative results arsults are identical with experimental results.
