Box 751 Portland，俄勒冈州97207- 0751摘要本提案旨在发展波特兰州立大学纳米科学与技术的综合研究、教育和推广计划，重点是碳纳米管研究。本研究的主要目标是：（i）开发一种可靠的方法来合成性能可控的碳纳米管;（ii）研究各种形式的纳米管作为制备条件的函数的生长机制，并建立微观结构和制备条件之间的相关性;（iii）研究碳纳米管的电子场发射性能与其几何构型的关系;（iv）研究碳纳米管的电子场发射性能。（iv）制造单独的碳纳米管场致发射体，并利用它们作为电子束仪器（例如TEM、SEM和电子束光刻系统）的电子源。这项研究的创新方面是1到联合收割机纳米管合成，微观结构表征，电子场发射测量，和单个纳米管场发射器制造成一个单一的项目，2探索电子束仪器的特殊要求，而不是平板显示器。这种方法的有效性在于，每个阶段的进展都将提供即时反馈，以推动其他阶段的改进。该研究计划是高度多学科的，涉及与物理，化学和电气工程部门，与太平洋西北国家实验室，并与当地的高科技公司（FEI）的同事密切合作。一个博士除了每年有八名本科生和两名高中生有机会参加研究活动外，还将通过该方案培训一名研究生。他们都将接受优秀的培训，为科学和工程事业做准备。该计划的教育目标包括：（i）结合研究成果开发新课程。将开发新课程，向学生介绍最新知识和最先进的技术; ㈡让大学生和高中生参与（特别是女学生）参与研究和科学教育活动，并鼓励她们从事科学和工程事业;（三）与当地教育机构合作，丰富外联活动，提高当地公民对未来的认识纳米科学和纳米技术的影响。

Title Integration of Nanoscience and Nanotechnology Research, Education, and Outreach: Systematic Tailoring of Carbon Nanotubes to Designed Electronic PropertiesInvestigator Jun JiaoSponsor Portland State UniversityP.O. Box 751Portland, Oregon 97207-0751Abstract This proposal aims at the development of an integrated research, education, and outreach program in nanoscience and technology at Portland State University, with an emphasis on carbon nanotube research. The objectives of the proposed research are focused on (i) developing a reliable method for synthesizing carbon nanotubes of controlled properties; (ii) studying the growth mechanisms of various forms of nanotubes as a function of preparation conditions, and establishing the correlation between microstructure and preparation conditions; (iii) investigating the electron field-emission properties of carbon nanotubes in relation to their geometrical configurations; (iv) fabricating individual carbon-nanotube field emitters and exploiting their use as electron sources for electron-beam instruments such as TEM, SEM, and electron-beam lithography systems. The innovative aspects of this research are 1 to combine nanotube synthesis, microstructural characterization, electron field-emission measurements, and individual nanotube field emitter fabrications into a single project, and 2 to explore the special requirements of electron-beam instruments, as opposed to flat-panel displays. The effectiveness of this approach is that progress at each stage will provide immediate feedback to advance the improvement of the others. The research program is highly multidisciplinary, involving close collaboration with colleagues in Physics, Chemistry and Electrical Engineering Departments, with Pacific Northwest National Laboratory, and with a local high-tech company (FEI). One Ph.D. graduate student will be trained through this program, in addition to eight undergraduate students and two high school students who will each year be offered opportunities to participate in the research activities. All of them will receive excellent training in preparation for careers in science and engineering.The educational objectives of this program include (i) incorporating research findings to develop a new curriculum. New courses, introducing students to up-to-date knowledge and state-of-the-art techniques, will be developed; (ii) involving undergraduate and high school students (in particular, female students) in research and science-education activities, and motivating them to pursue careers in science and engineering; (iii) enriching outreach activities by collaborating with local educational institutions to increase the awareness of local citizens with regard to the future impact of nanoscience and nanotechnology.
