| 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 are identical with experimental results. |
| Keywords: | optoelectronics photoconductive detector instantaneous change behavior heat equilibrium carriers photoconductive carriers |
