Title: Acquisition of a Cathodoluminescence System for Materials Research, Device Testing and EducationThis proposal application to the Major Research Instrumentation (MRI) Program requests support of the University of Central Florida (UCF) in acquisition of the state-of-the-art Allalin 4027 Chronos Cathodoluminescence Electron Microscope manufactured by Attolight AG for continuous and pulsed (time-resolved) in-situ characterization of a wide-range of materials and devices with nano-scale resolution. Abstract:Cathodoluminescence (CL) is the light emitted by specimens, as a result of electron bombardment, in the wavelength range of 160 to 2000 nm. This broad spectral range allows CL to be collected from a wide variety of materials including metals, semiconductors and biological samples, as well as devices based on them. The proposed CL Electron Microscope will be employed for optical testing of materials and devices and will support the mission of UCF, a comprehensive state university committed to providing quality education, engaging in beneficial research and integrating the university's education, research and training programs with the local community. As of 2016, UCF is the second largest university in the US and the second largest in the state of Florida to grant M.Sc. and Ph.D. degrees in Materials Science and Engineering. Consequently, there has been a significant need for curriculum development and enhancement to establish comprehensive physics, optics, photonics and materials science programs. Because of the large number of students involved, there is a number of specialty graduate level courses given on advanced devices and materials technologies. The proposed CL Microscope will form the basis of new laboratory course to train students in the theory, methodology and data analysis possible with this new and versatile state-of-the-art equipment. It should be noted that UCF hosts several NSF programs with as much as 68% students from under-represented groups. Therefore, an involvement of the proposed Attolight Microscope in these programs will also promote training of minority students in top-edge research projects. If this project is successful, the proposed CL Microscope will be the first one ever deployed in the North and South America, thus demonstrating the broader impact of the instrument on the research community at the regional, national and international levels. The proposed CL instrument will be an essential piece of equipment for characterization of novel materials and functional structures such as semiconductor and plasmonic devices as well as ceramic microstructures and defects. The advantage of the proposed system is also in its capabilities of studying various organic materials. The proposed CL Microscope will allow unprecedented nano-scale imaging and in-depth understanding of non-equilibrium electronic carrier dynamics (down to pico-second time scale) and transport in a wide range of materials and devices. This understanding constitutes the main intellectual merit of the proposed NSF-MRI project. The proposed system will additionally advance a number of research efforts in photonics and materials science at UCF. Hence, such a tool will provide a fundamental, multi-disciplinary and versatile capability that is presently lacking at the University of Central Florida, thus emphasizing the broader impact of this MRI proposal.

标题：采购用于材料研究、设备测试和教育的阴极发光系统本提案申请主要研究仪器 (MRI) 计划，请求中佛罗里达大学 (UCF) 支持采购最先进的 Allalin 4027 Chronos 阴极发光电子显微镜由 Attolight AG 制造，用于以纳米级分辨率对各种材料和器件进行连续和脉冲（时间分辨）原位表征。摘要：阴极发光（CL）是样品因电子轰击而发出的光，波长范围为 160 至 2000 nm。这种宽光谱范围允许从各种材料中收集化学发光，包括金属、半导体和生物样品以及基于它们的设备。拟议的 CL 电子显微镜将用于材料和器件的光学测试，并将支持中佛罗里达大学的使命，中佛罗里达大学是一所综合性州立大学，致力于提供优质教育，从事有益的研究，并将大学的教育、研究和培训项目与当地的教育、研究和培训项目相结合。社区。截至 2016 年，UCF 是美国第二大大学，也是佛罗里达州第二大授予硕士学位的大学。和博士学位。材料科学与工程学位。因此，迫切需要开发和加强课程，以建立综合的物理、光学、光子学和材料科学课程。由于涉及的学生人数众多，因此开设了许多有关先进器件和材料技术的专业研究生水平课程。拟议的 CL 显微镜将构成新实验室课程的基础，以培训学生使用这种新型多功能最先进设备进行理论、方法和数据分析。值得注意的是，UCF 举办了多个 NSF 项目，其中多达 68% 的学生来自代表性不足的群体。因此，拟议的 Attolight 显微镜参与这些项目也将促进对少数族裔学生进行尖端研究项目的培训。如果该项目成功，拟议的 CL 显微镜将成为北美和南美首次部署的显微镜，从而展示该仪器对区域、国家和国际层面研究界的更广泛影响。所提出的 CL 仪器将成为表征新型材料和功能结构（例如半导体和等离子体器件以及陶瓷微观结构和缺陷）的重要设备。该系统的优点还在于其研究各种有机材料的能力。所提出的 CL 显微镜将实现前所未有的纳米级成像，并深入了解非平衡电子载流子动力学（低至皮秒时间尺度）以及各种材料和设备中的传输。这种理解构成了拟议的 NSF-MRI 项目的主要智力优点。拟议的系统还将进一步推进中佛罗里达大学光子学和材料科学方面的多项研究工作。因此，这样的工具将提供中佛罗里达大学目前缺乏的基本的、多学科的和多功能的能力，从而强调了该 MRI 提案的更广泛影响。
