摘要
为了表征噪声对量子点红外探测器性能的影响,本文推导了噪声的理论模型.该模型通过考虑纳米尺度电子传输和微米尺度电子传输对激发能的共同影响,并结合噪声增益,实现了对噪声的估算.得到的结果与实验的数据相比,显示了很好的一致性,从而验证了这个模型的正确性.
A theoretical model for the noise is derived in this paper to characterize the influence of the noise on quantum dot infrared photodetectors. In this model, the noise current is estimated with the consideration of the common influence of the nanoscale electron transport and microscale electron transport on the activation energy and the contribution of the noise gain. The obtained results show a good agreement with the published experimental values, which illustrates the validity of the model.
