1. PROJECT SUMMARYWe request funds to acquire a scanning electron microscope that will be capable of high-resolutionelectron imaging and cathodoluminescence spectroscopy and imaging (CL) with 1 nmresolution. The proposed instrument will be located in the cleanroom (Class 100) in the Microand Nanotechnology Laboratory at the University of Illinois at Urbana-Champaign. TheLaboratory is an interdisciplinary research user facility that houses advanced equipment formaterials and device processing. The laboratory has been very successful in facilitating cross-disciplinaryresearch and collaborations. Over 40 faculty, 20 postdoctoral fellows, 200 graduatestudents, and many undergraduates have access to the laboratory. The users span across variousdisciplines and departments on campus. The user list is steadily growing as we facilitatediscussions between various groups on the versatility of nanotechnology. Personnel fromneighboring academic institutions are users of the laboratory also.The availability of the proposed SEM+CL system is critical to many research programs active atthe University of Illinois. Three illustrative examples of these research programs are described indetail. These are:Nanoscale Pattern Formation in Soft Materials (John Rogers and Ilesanmi Adesida)Nanophotonics: Quantum Dots and Photonic Crystals (James Coleman and KentChoquette)Silicon Bionanotechnology (Gregory Timp)Various other projects make use of the facilities in the laboratory and among these are theprojects that have recently being started under the newly awarded NSF Center for Nano-Chemical-Electrical-Mechanical Manufacturing Systems (Nano-CEMMS) at the University ofIllinois. The proposed research instrumentation is vital to these projects since they involvefabrication at length scale less than 20 nm.The intellectual merit of this proposal is in the new science and innovations that will befacilitated. The proposed instrumentation will enable imaging and spectroscopy at the nano-regime;understanding phenomena in organic and inorganic structures and systems at this scalewill open a vista to new applications. The proposed instrumentation will facilitate collaborationsacross various disciplines and the research will lead wide-ranging applications in medicine, food,environment and electronics.For the broader impact, the proposed instrument will see significant use ingraduate/undergraduate research and education programs. Minority and under-representedstudents will be recruited through various mechanisms involving our campus-wide SummerResearch Opportunity Program (SROP) and through our collaborative programs with minorityserving universities in Centers such as the Nano-CEMMS. Faculty from these schools will haveaccess to the laboratory through these Centers also. Programs for k-12 teachers to conductsummer research in the laboratory with access to the research instrumentation is in place. Self-operationof the equipment by all qualified researchers regardless of institutional/departmentalaffiliations or source of funding is encouraged so as to enhance their education. With theavailability of the proposed instrumentation, we envisage an increase in usage by andcollaborations with industry.The total estimated cost of acquiring the proposed instrument is $688,338. Of this amount, we arerequesting $481,837 from the National Science Foundation. The University of Illinois willprovide cost sharing of $206,501 (30.0 %) of the total cost of the instrument.

1。项目Summarywe请求资金以获取扫描电子显微镜，该扫描电子显微镜将能够具有1 nmresolution的高分辨率电子成像和阴极发光光谱和成像（CL）。该拟议的乐器将位于伊利诺伊大学Urbana-Champaign大学的微型纳米技术实验室的洁净室（100级）。 Thelaboratory是一个跨学科的研究用户设施，可容纳先进的设备形式和设备处理。该实验室在促进跨学科研究和合作方面非常成功。超过40多名教职员工，20名博士后研究员，200名毕业生和许多本科生可以进入实验室。用户跨越校园的各个学科和部门。当我们在各组之间促进纳米技术的多功能性之间，用户列表正在稳步增长。来自沃姆堡学术机构的人员也是实验室的用户。拟议的SEM+CL系统的可用性对于伊利诺伊大学活跃的许多研究计划至关重要。这些研究计划的三个说明性示例被描述为不详细信息。这些是：软材料中的纳米级图案形成（John Rogers和Ilesanmi adesida）纳米光子学：量子点和光子晶体（James Coleman和Kentchoquette）硅Bionanotechnology（Gregory Timp）纳米化学电力机械制造系统（纳米cemms）在伊利诺伊大学。拟议的研究工具对这些项目至关重要，因为它们涉及到尺寸小于20 n的时间范围。该提案的智力优点在新的科学和创新中，这将引起人们的影响。所提出的仪器将在纳米礼节上启用成像和光谱；在此规模上了解有机和无机结构和系统中的现象，将向新应用打开远景。拟议的仪器将促进各种学科的合作，该研究将领导医学，食品，环境和电子产品方面的广泛应用。对于更广泛的影响，该拟议的工具将看到大量使用Indradeute/Indradeute/Inderfradeute Research and Education计划。将通过涉及我们校园范围内的Summersearch机会计划（SROP）的各种机制以及与我们与纳米cemms等中心的少数派大学的合作计划来招募少数群体和代表性不足的学生。这些学校的教师也将通过这些中心向实验室提供。 K-12教师在实验室进行研究仪器进行研究的计划。所有合格的研究人员的设备自我开放，无论机构/部门的交易所或资金来源如何，以增强他们的教育。随着拟议仪器的征服性，我们设想通过行业和行业的情况增加使用的使用。获取该工具的总估计成本为688,338美元。在这笔款项中，我们从国家科学基金会（National Science Foundation）拨出481,837美元。伊利诺伊大学将保留该工具总成本的206,501美元（30.0％）的成本分配。
