Nontechnical descriptionMetal nanostructures can confine light into very small spaces near their surfaces and enable a diverse range of applications, from the color of stained glass in the Middle Ages to new classes of nanoscale-sized lasers. Understanding the optical properties of assemblies of metal nanoparticles is important to advance current light-based technologies. This project aims to design and fabricate new architectures based on multilayer nanoparticle arrays that can be optically excited and to realize nanoparticle-based devices that can be integrated with electrical circuits. The project will train a diverse research team of graduate and undergraduate students in optical device system design, fabrication, and characterization techniques in state-of-the-art facilities coupled with advanced theoretical modelling and science communication. The principal investigators actively recruit students from different backgrounds, which fosters inclusion, retention, and advancement of underrepresented and marginalized students. The research team hosts multiple educational outreach events on the Northwestern University campus to make light-based research accessible to younger students and to encourage them to consider careers in STEM-related fields.Technical descriptionMany-body phenomena such as superconductivity or light-induced ferromagnetism are a couple examples of the unique properties displayed by vertically stacked 2D materials that are absent in their monolayer form. Inspired by the exotic properties of 2D stacked electronic materials, this project aims to develop stacked and twisted plasmonic nanoparticle structures to explore: (1) how bound states in the continuum can enable macroscale, long-range light manipulation; (2) how stacked lattices couple out-of-plane and how their properties depend on relative twist angle; and (3) how electrical excitation of plasmonic lattices can be combined with 2D electronic materials to enable chip-based plasmonic systems. The design of sophisticated plasmonic lattice architectures is fundamental to understanding short- and long-range coupling of nanoparticle unit cells and can facilitate novel applications in functional photonic devices, such as mechanical manipulation and electrical pumping. The realization of electrical excitation of plasmons is of particular technological interest in order to bridge the gap between nanophotonic and microelectronic devices. Broader impacts of this project will build on knowledge gained for applications related to coherent emission, long-range energy transfer, and quantum coherence.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.

金属纳米结构可以将光限制在其表面附近的非常小的空间内，并实现各种各样的应用，从中世纪的彩色玻璃到新型的纳米级激光器。了解金属纳米粒子组装的光学性质对于推进当前的光基技术非常重要。该项目旨在设计和制造基于多层纳米颗粒阵列的新架构，这些纳米颗粒阵列可以被光激发，并实现可以与电路集成的基于纳米颗粒的设备。该项目将在最先进的设施中培训由研究生和本科生组成的多元化研究团队，掌握光学器件系统设计、制造和表征技术，并结合先进的理论建模和科学传播。主要研究人员积极招募来自不同背景的学生，促进包容，保留和代表性不足和边缘化学生的进步。该研究团队在西北大学校园举办了多场教育推广活动，让年轻学生能够接触到基于光的研究，并鼓励他们考虑从事STEM相关领域的职业。技术支持超导或光致铁磁性等多体现象是垂直堆叠的2D材料所展示的独特性质的几个例子，这些材料在单层形式下是不存在的。受2D堆叠电子材料的奇异性质的启发，该项目旨在开发堆叠和扭曲的等离子体纳米颗粒结构，以探索：（1）连续体中的束缚态如何实现宏观尺度，远程光操纵;（2）堆叠晶格如何耦合出平面以及它们的性质如何依赖于相对扭曲角;（3）如何在不同的时间间隔内实现量子点的量子化。以及（3）等离子体晶格的电激发如何与2D电子材料组合以实现基于芯片的等离子体系统。复杂的等离子体晶格结构的设计是理解纳米粒子单元的短程和长程耦合的基础，并且可以促进功能光子器件中的新应用，例如机械操纵和电泵浦。实现等离子体激元的电激发具有特别的技术兴趣，以便桥接纳米光子器件和微电子器件之间的差距。该项目的更广泛影响将建立在与相干发射、远程能量传输和量子相干相关的应用所获得的知识之上。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
