Mercury Cadmium Telluride (MCT) is a primary absorber material used in most infrared (IR) detection technologies. Our previous studies show that the optical absorbance profile of MCT in the mid-infrared region can be enhanced by 13% under ambient conditions via integrating periodic Indium Tin Oxide (ITO) nanostructures. Here, we focus on the geometrical parameterization and optimization of ITO nanostructure arrays. We simulate several types of geometries, their corresponding effective absorption profiles, E-field distribution, and optimal geometric parameters. This work may lead to improved light collection and absorption edge engineering, as MCT continues to be the material of choice in IR detection architectures.

MWIR HgCdTe（MCT）上的等离子体纳米结构阵列的几何优化

碲化汞镉（MCT）是大多数红外（IR）检测技术中使用的主要吸收材料。我们以前的研究表明，在环境条件下，通过整合周期性的氧化铟锡（ITO）纳米结构，MCT在中红外区域的光吸收曲线可以提高13％。在这里，我们专注于ITO纳米结构阵列的几何参数化和优化。我们模拟了几种类型的几何形状，它们对应的有效吸收曲线，电场分布和最佳几何参数。随着MCT继续成为红外检测架构中的首选材料，这项工作可能会改善光收集和吸收边缘的工程性。
