量子点红外探测器的光电流和响应率（英文）

Photocurrent and responsivity of quantum dot infrared photodetectors

通过考虑光电导增益对探测器所加电压的依赖性改进了包含电子持续势能和总电子传输的光电流模型,并进一步将这个改进的模型用于估算探测器的响应率.相应的计算结果与公布的结果相比较,具有很好的一致性,证明了改进模型的正确性.

In this paper,a model for the photocurrent of the quantum dot infrared photodetector（ QDIP） including the continuous potential distribution of the electrons and the total electron transport is improved with the consideration of the dependence of the photoconductive gain on the applied bias,and this improved model can be further used to estimate the responsivity of the photodetector. The corresponding calculated results showa good agreement with the published results,which verifies the validity of the improved model.
