摘　　要：红外探测器吸收性能的相关研究一直是备受关注的研究领域,吸收率仍存在进一步提升的潜力。设计了金属-半导体-金属(MSM)型量子阱红外探测器结构,并在仿真软件中模拟计算了其吸收率。结果表明,该结构可以在特定频率下发生法布里-珀罗共振(FP共振)且明显增强了吸收。此外,量子阱的层数和入射角度等因素会对FP共振频率产生影响,且在量子阱层数为7层、入射角在0°~15°之间时,所设计的MSM型量子阱红外探测器表现出最佳的吸收性能。Studies related to the absorption performance of infrared detectors have been a research area of great interest,and there is still potential for further improvement of the absorption rate.In this study,a metal-semiconductor-metal(MSM)-type quantum well infrared detector structure was designed and its absorption rate was simulated and calculated in simulation software.The results show that the structure can undergo Fabry-Perot resonance(FP resonance)at a specific frequency and enhance the absorption significantly.In addition,factors such as the number of layers of the quantum well and the angle of incidence affect the FP resonance frequency,and the designed MSM-type quantum well infrared detector exhibits the best absorption performance when the number of layers of the quantum well is 7 and the angle of incidence is between 0°and 15°.
