Optimization of Quantum Dot Infrared Photodetectors Based on Noise Model

Abstract:

As an important property of the quantum dot infrared photodetector, the noise has attracted extensive attention. In this paper, the model for the noise of the QDIP is built. This model takes the total electron transport and the dependence of the drift velocity of electrons on the electric field into account. The corresponding calculated results not only show a good agreement with the published results, but also illustrate the dependence of the noise on the structure which can provide us with a method used to optimize the structure of the detector devices.
