摘要：

Quantum dot infrared photodetectors (QDIPs) have already attracted more and more attention in recent years due to its superior performance. In this paper, a model for the dark current of the QDIP is built. This model supposes that the dark current in the potential barriers is equal to the dark current of the total device according to the structure of the QDIP, and the total electrons transport, the drift velocity and the mobility dependences on the electric field are also taken into account. The corresponding results show the correctness and the validity of the dark current model.
