NON-TECHNICAL DESCRIPTION: Metamaterials, hybrid materials made of nanoscale inclusions, can exhibit exotic optical responses, and enable promising applications such as super lenses, optical sensors, and subwavelength imaging. To date, most metamaterials are created using costly and tedious lithography and fabrication techniques, and involve lossy metallic materials with high dissipative losses and heating. Leveraging the expertise in the PI’s group in processing self-assembled, nanoscale oxide-oxide and oxide-metal hybrid thin films in a vertically aligned nanocomposite (VAN) form, the project develops a new class of novel hybrid materials with all ceramic phases, i.e., oxide-nitride VANs, to address the urgent needs of optical metamaterials with low dissipative losses and operating over a broad wavelength range. The education and outreach activities are integrated with the research, including 1) engaging undergraduates in research; 2) multidisciplinary research training for students at both Purdue and national labs; and 3) disseminating research findings to broad audiences by (a) involving underrepresented groups in materials science and engineering, (b) attracting high school students into materials science through laboratory demonstrations, lectures at science festivals and materials art galleries, (c) developing web-based tools for research group websites and inclusion in NanoHUB.TECHNICAL DETAILS: This project focuses on the design, synthesis, and characterization of metal-free hybrid metamaterials in the VAN thin film form. The goal of the project is to achieve all-ceramic hybrid metamaterials with tunable physical properties, especially optical, magnetic and magneto-optical coupling properties. The specific tasks include: (1) exploring in-plane spontaneous ordering of oxide-nitride hybrid VANs; (2) enabling nanopillar geometry control towards designable hybrid materials with high degree of property tunability; and (3) targeting unprecedented 3D hybrid material designs via multilayer stacking of the VANs. Besides the fundamental design criteria and morphology control approaches developed for the all ceramic hybrid metamaterials, the research offers several technological impacts: (1) metal-free hybrid metamaterial designs are critical for a wide range of optical applications requiring low dissipation losses, high thermal stability, chemical inertness, and multifunctionality; (2) novel hybrid metamaterials may find applications as classical optical interconnects, waveguides, integrated photonics, and all-on-chip optical circuits; and (3) magnetic hybrid metamaterials may be used in high density magnetic data storage, magnetic sensors, and spintronics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术描述：超材料是由纳米级夹杂物制成的混合材料，可以表现出奇特的光学响应，并实现超级透镜、光学传感器和亚波长成像等有前景的应用。迄今为止，大多数超材料都是使用昂贵且繁琐的光刻和制造技术制造的。技术，并涉及具有高耗散损耗和加热的有损金属材料，利用 PI 团队在处理自组装、纳米级氧化物和氧化物方面的专业知识。该项目开发了一种新型全陶瓷相的新型混合材料，即氧化物-氮化物VAN，以解决对低耗散损耗光学超材料的迫切需求教育和推广活动与研究相结合，包括 1) 让本科生参与研究；2) 为普渡大学和国家实验室的学生提供多学科研究培训； 3）通过以下方式向广大受众传播研究成果：（a）让材料科学与工程领域代表性不足的群体参与进来，（b）通过实验室演示、科学节和材料艺术画廊的讲座吸引高中生进入材料科学，（c）开发网络-基于研究小组网站的工具并包含在 NanoHUB 中。技术细节：该项目重点关注 VAN 薄膜形式的无金属混合超材料的设计、合成和表征。该项目的目标是实现。具有可调谐物理特性，特别是光学、磁和磁光耦合特性的全陶瓷混合超材料，具体任务包括：（1）探索氧化物-氮化物混合VAN的面内自发有序性；（2）实现纳米柱几何控制。具有高度性能可调性的可设计混合材料；(3) 除了为全陶瓷混合材料开发的基本设计标准和形态控制方法外，还通过 VAN 的多层堆叠实现前所未有的 3D 混合材料设计。超材料，该研究提供了几个技术影响：（1）无金属混合超材料设计对于需要低耗散损耗、高热稳定性、化学惰性和多功能性的广泛光学应用至关重要；（2）可能会发现新型混合超材料；经典光学互连、波导、集成光子学和全片光学电路等应用；(3) 磁性混合超材料可用于高密度磁性数据存储、磁传感器和自旋电子学。通过使用基金会的智力价值和更广泛的影响审查标准进行评估，NSF 的法定使命被认为值得支持。
