摘要

模拟了n+-p+ Hg1−xCdxTe中波长红外(MWIR)异质结光电探测器在T=295 K时的性能，以评估其电学和光学特性。利用SILVACO ATLAS 2D软件对该装置进行了仿真和优化。通过适当的偏置和优化器件厚度，可以显著降低暗电流，从而将量子效率和响应率分别提高到78.7%和3.1 A/W左右。

Simulation and optimization of Hg1−xCdxTe based mid-wavelength IR photodetector

The performance of n+-p+ Hg1−xCdxTe midwavelength infrared (MWIR) heterojunction photodetector at T=295 K is simulated to evaluate the electrical and optical characteristics. The SILVACO ATLAS 2D software has been used for the simulation and optimization of the device. The dark current has been reduced significantly by applying suitable biasing and optimizing the device thickness which in turn improves quantum efficiency and responsivity to be around 78.7 % and 3.1 A/W, respectively.
