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:获取用于材料研究、设备测试和教育的阴极发光系统这是一项向主要研究仪器（MRI）项目提出的申请，要求中佛罗里达大学（UCF）获得最先进的Allalin 4027 Chronos阴极发光电子显微镜的支持，该显微镜由Attolight AG公司制造，用于连续和脉冲（时间分辨）原位表征各种纳米级分辨率的材料和设备。摘要：阴极发光（CL）是样品在电子轰击作用下发出的波长范围为160 ~ 2000 nm的光。这种广泛的光谱范围允许从各种各样的材料中收集CL，包括金属，半导体和生物样品，以及基于它们的设备。拟议中的CL电子显微镜将用于材料和器件的光学测试，并将支持UCF的使命，UCF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，研究和培训计划与当地社区相结合。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材料科学与工程硕士和博士学位的大学。因此，有必要开发和加强课程，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，因此有许多关于先进器件和材料技术的专业研究生课程。拟议的CL显微镜将形成新的实验课程的基础，以培养学生的理论，方法和数据分析可能与这个新的和多功能的最先进的设备。应该指出的是，UCF举办了几个国家科学基金会项目，其中68%的学生来自代表性不足的群体。因此，在这些项目中加入光学显微镜也将促进少数民族学生在尖端研究项目中的培训。如果该项目成功，拟议中的CL显微镜将成为北美和南美首次部署的显微镜，从而展示了该仪器在区域、国家和国际层面上对研究界的更广泛影响。所提出的CL仪器将成为表征新材料和功能结构（如半导体和等离子体器件）以及陶瓷微结构和缺陷的重要设备。该系统的优势还在于其研究各种有机材料的能力。提出的CL显微镜将允许前所未有的纳米级成像和深入了解非平衡电子载流子动力学（低至皮秒时间尺度）和广泛的材料和器件中的传输。这种理解构成了拟议的NSF-MRI项目的主要智力价值。该系统将进一步推动UCF在光子学和材料科学方面的研究工作。因此，这种工具将提供一个基础的、多学科的、多功能的能力，这是目前佛罗里达中央大学所缺乏的，因此强调了MRI提议的更广泛的影响。
