Nontechnical AbstractCarbon nanotubes are becoming an increasingly important nanomaterials system for technological translation: over the last ten years, research in the growth and alignment of carbon nanotubes has led to the demonstration of advanced integrated electronic systems such as carbon nanotube computer processors. An important complement to electronic functionality is optical functionality, where carbon nanotubes have the potential to generate, detect, and guide light for use in sensors and communication modules, in a manner that seamlessly integrates with carbon nanotube-based electronic logic devices. The proposed work will explore the ability for nanotubes to serve as advanced optoelectronic devices at infrared wavelengths. In particular, the fundamental limits for guiding and localizing light will be elucidated using new computational methods and new experimental materials preparation and characterization methods. The education goal of this project is to work with grade school teachers to disseminate new curricula that educates and inspires high school students in STEM.Technical AbstractThe ultimate limits of plasmon propagation and compression in one-dimensional systems remain elusive. The related open questions include fundamental aspects of plasmonic excitations such as their lifetimes, dynamics, and quantum plasmonic dispersion in one-dimensional single-walled carbon nanotubes (SWCNTs) and mixed-dimensional systems. We propose to establish new methodologies, based on advanced materials growth and nanofabrication methods, high-resolution optical probing, and high-performance first-principles calculations, to elucidate the underlying physics of strongly confined one-dimensional plasmonic systems. The study builds on our development and study of chemical vapor deposition-grown wafer-scale SWCNTs and near-field optical instrumentation. This project will lead to new fundamental understandings of one-dimensional quantum plasmons, its coupling with other plasmonic systems, the relevant correlated physics within the quantum confined Luttinger liquid regime. We also anticipate that our newly developed experimental and theoretical methods will broadly apply to the study of other condensed matter systems.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.

碳纳米管正在成为一种越来越重要的纳米材料系统，用于技术转化：在过去的十年中，对碳纳米管生长和排列的研究已经导致了先进的集成电子系统如碳纳米管计算机处理器的示范。 电子功能的一个重要补充是光学功能，其中碳纳米管有可能产生，检测和引导用于传感器和通信模块的光，与基于碳纳米管的电子逻辑器件无缝集成。 拟议的工作将探索纳米管作为红外波长的先进光电器件的能力。 特别是，将使用新的计算方法和新的实验材料制备和表征方法阐明引导和定位光的基本限制。 该项目的教育目标是与小学教师合作传播新课程，教育和激励高中生学习STEM。技术摘要一维系统中等离子体激元传播和压缩的最终极限仍然难以捉摸。相关的开放性问题包括等离子体激元激发的基本方面，如它们的寿命，动力学和量子等离子体激元分散在一维单壁碳纳米管（SWCNT）和混合维系统。 我们建议建立新的方法，基于先进的材料生长和纳米加工方法，高分辨率的光学探测，和高性能的第一性原理计算，以阐明强约束的一维等离子体系统的基本物理。 这项研究建立在我们的化学气相沉积生长晶圆级单壁碳纳米管和近场光学仪器的发展和研究。 该项目将导致一维量子等离子体激元的新的基本理解，它与其他等离子体激元系统的耦合，量子限制Luttinger液体制度内的相关物理。 我们也期望我们新开发的实验和理论方法将广泛应用于其他凝聚态物质系统的研究。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。
