项目摘要

National Science Foundation - Division of Chemical &Transport Systems Particulate & Multiphase Processes Program (1415)Proposal Number: 0651780 Principal Investigators: Jiang, Peng Affiliation: University of Florida Proposal Title: Shear-Aligned Assembly of Photonic Band Gap Coating Intellectual MeritThis proposal aims to develop understanding and control of a robust spin-coating technology that enables large-scale production and integration of photonic crystals and a diverse range of nanostructured materials. Although simpler and less expensive than nanolithography for creating photonic crystals, the colloidal self-assembly approach suffers from low throughput and limited crystal structures. By contrast, the spin-coating method developed by the PI combines the simplicity and cost benefits of traditional self-assembly with the scalability and compatibility of nanolithography, allowing for the creation of wafer-scale colloidal crystals with non-close-packed structures.The mechanism by which the colloidal single crystals, with remarkably large domain sizes and unusual non-close-packed structures, form is not understood. Consequently, the research team will perform an experimental and theoretical investigation of the shear-aligned crystallization process. The team will employ light diffraction, laser scanning confocal microscopy, optical spectroscopy, and rheology to elucidate the microstructures and disorder-order transition during spin-coating. The team will use Stokesian dynamics simulations to model the applied hydrodynamic, colloidal, and Brownian forces; the microstructures and rheological properties of colloidal dispersions subjected to uniform and non-uniform shear flow, as appropriate for the spin-coating process, will be calculated. The photonic band gaps of the photonic crystals will be compared with theoretical calculations using scalar wave approximation and the MIT Photonic-Bands package.Broader ImpactThe proposed research program will lead to significant breakthroughs in fabricating and integrating photonic-crystal-based nanooptical devices for all-optical integrated circuits and quantum information processing, as well as important technological applications in subwavelength optics, plasmonic sensors, efficient OLEDs and photovoltaics, high-density magnetic recording media, and bio-microanalysis. Improved understanding of the fundamental aspects of flow-induced crystallization, melting, and relaxation within non-uniform shear flows, a topic that has received little or no examination, will also result.The educational program will impact students at all education levels. Outreach efforts through a local museum will bring modern technology to young students and adults through a fun learning experience and participation of high school students in the research program will benefit the students and their larger communities. Finally, collaborative efforts with high school teachers to develop classroom materials will favorably impact numerous students at the secondary level.
美国国家科学基金会-化学传输系统部颗粒多相过程计划(1415)提案编号:0651780主要研究者:姜鹏单位: 佛罗里达大学提案标题:剪切对齐组装光子带隙涂层知识产权MeritThis提案旨在发展一个强大的旋涂技术,使大规模生产和集成的光子晶体和各种各样的纳米结构材料的理解和控制。虽然比用于产生光子晶体的纳米光刻更简单且更便宜,但胶体自组装方法遭受低产量和有限的晶体结构。相比之下,PI开发的旋涂方法结合了传统自组装的简单性和成本优势与纳米光刻的可扩展性和兼容性,允许创建具有非紧密堆积结构的晶圆级胶体晶体。胶体单晶具有非常大的域尺寸和不寻常的非紧密堆积结构,形成的机制尚不清楚。因此,研究小组将对剪切取向结晶过程进行实验和理论研究。该团队将采用光衍射,激光扫描共聚焦显微镜,光谱学和流变学来阐明旋涂过程中的微观结构和无序-有序转变。该团队将使用斯托克斯动力学模拟来模拟应用的流体动力学,胶体和布朗力;将计算胶体分散体的微观结构和流变特性,这些胶体分散体将受到均匀和不均匀的剪切流,适用于旋涂工艺。更广泛的影响拟议的研究计划将导致在制造和集成光子晶体为基础的纳米光学器件的全光集成电路和量子信息处理的重大突破,以及重要的技术应用在亚波长光学,等离子体传感器,高效OLED和光致发光器件、高密度磁记录介质和生物微量分析。提高对非均匀剪切流中流动诱导结晶、熔化和松弛的基本方面的理解,这是一个很少或根本没有考试的主题。教育计划将影响所有教育水平的学生。通过当地博物馆进行的外展工作将通过有趣的学习体验为年轻学生和成年人带来现代技术,高中生参与研究项目将使学生及其更大的社区受益。最后,与高中教师合作开发课堂材料将对中学一级的许多学生产生有利影响。
