| 摘 要： | 提出了改进的描述光伏型半导体光电探测器中载流子输运的漂移-扩散模型，该模型能适合更高强度的激光辐照，可以模拟光生载流子的长时间过程。依据该模型，对光伏型探测器进行了模拟计算，得到了激光辐照下探测器的动态响应规律、探测器温升以及材料参数对探测器响应的影响。

| Abstract: | Improved drift-diffusion model to describe the carrier transportation in photovohaic semiconductor detectors under any power laser irradiation has been proposed. The model is capable of simulating the long processes of photocarriers transportation. Simulation calculations for photovohaic semiconductor detector have been carried out according to the model. Dynamic response characteristics,and the influences of temperature rise and material parameters on the responses of the detector under laser irradiation are obtained. The theoretical results are in agreement with the experimental ones. |
