GOALI/Collaborative Research: Antenna-Coupled ALD-Enabled Metal-Insulator-Insulator-Metal Diodes for High Responsivity and High Resolution THz/Infrared Focal Plane ArraysThe objective of this research is to develop a new class of room temperature metal-insulator-insulator-metal tunnel diode detectors and monolithically integrate them within novel miniature antenna focal plane array configurations for high resolution and high responsivity THz/infrared imaging as well as energy harvesting. The approach is to enhance nonlinearity of the diodes up to 30THz by using dual tunnel junctions and employ a system level design by addressing issues of antenna-diode impedance mismatches, compact antenna size, inter-element electromagnetic couplings, and bandwidth.Intellectual Merits:The program is focused on challenges associated with system-level integration of antenna coupled metal-insulator-insulator-metal diodes for high performance THz/infrared imaging. Metal-insulator-insulator-metal diodes offering sensitive detection of radiation up to 30THz will advance the synthesis of ultrathin dielectric materials and nanofabrication. The critical goals of high resolution and high responsivity will be achieved through novel approaches in antenna miniaturization, non-uniform array layouts, and compact impedance matching networks. Ultra-wideband imaging and energy harvesting will be accomplished with novel broadband arrays and computational electromagnetics modeling. Broader Impacts:The outcomes will impact a broad range of applications including environmental, biomedical, material science, homeland security, and renewable energy. The effort is well aligned with synergistic research in the area of medical THz imaging and infrared renewable energy at both universities. The industry partnership will allow to broadly disseminate research results beyond the academic community. The project will provide a system level design opportunity to graduate students, impact the curriculum at both universities, and leverage ongoing programs to attract underrepresented students to engineering.

GOALI/合作研究：用于高响应度和高分辨率太赫兹/红外焦平面阵列的天线耦合 ALD 金属-绝缘体-绝缘体-金属二极管这项研究的目的是开发一种新型室温金属-绝缘体-绝缘体-金属隧道二极管探测器，并将它们单片集成到新型微型天线焦平面阵列配置中，以实现高分辨率和高响应度太赫兹/红外成像以及能量收集。该方法是通过使用双隧道结将二极管的非线性增强到 30THz，并通过解决天线-二极管阻抗失配、紧凑天线尺寸、元件间电磁耦合和带宽等问题来采用系统级设计。该计划的重点是解决与用于高性能太赫兹/红外成像的天线耦合金属-绝缘体-绝缘体-金属二极管的系统级集成相关的挑战。金属-绝缘体-绝缘体-金属二极管可灵敏检测高达 30THz 的辐射，将推动超薄介电材料的合成和纳米加工。高分辨率和高响应度的关键目标将通过天线小型化、非均匀阵列布局和紧凑阻抗匹配网络的新颖方法来实现。超宽带成像和能量收集将通过新型宽带阵列和计算电磁学建模来完成。更广泛的影响：研究结果将影响广泛的应用，包括环境、生物医学、材料科学、国土安全和可再生能源。这项工作与两所大学在医学太赫兹成像和红外可再生能源领域的协同研究非常一致。行业合作伙伴关系将使研究成果能够在学术界之外广泛传播。该项目将为研究生提供系统级设计机会，影响两所大学的课程，并利用正在进行的项目吸引代表性不足的学生进入工程学领域。
