MRI: Development of an Apertureless Near-Field Scanning Optical and Magneto-Optical Kerr Effect Microscope for Nano-Science Applications

该重大研究仪器奖支持圣母大学 (UND) 开发用于纳米科学应用的基于真空的无孔径近场扫描光学 (ANSOM) 和磁光克尔效应显微镜。该仪器继承了原子力显微镜和光学显微镜的优点，两者相辅相成。 迄今为止，商业供应商还没有提供这样的系统。尽管空气中的 ANSOM 已相当广泛地应用于研究纳米级材料的电子和光学特性，但它受到水污染和环境噪音的影响。 在真空中，预计电磁力和清洁环境的检测将得到几个数量级的改进。 真空ANSOM将被开发并应用于半导体线/点发射间歇性、纳米级磁光克尔效应等。 该仪器的开发需要 UND 六个以上研究小组的合作。 将设计各种项目，以在整个项目期间积极吸引研究生、本科生、K12 学生和教师。 开发阶段完成后，该仪器将安装在集中的 UND 集成成像设施中，更广泛的用户可以从其独特的功能中受益。******这项重大研究仪器奖支持圣母大学 (UND) 开发基于真空的无孔径近场扫描光学 (ANSOM) 和磁光克尔效应显微镜，用于纳米科学应用。该仪器继承了原子力显微镜和光学显微镜的优点，两者相辅相成。 迄今为止，商业供应商还没有提供这样的系统。尽管空气中的 ANSOM 已相当广泛地应用于研究纳米级材料的电子和光学特性，但它受到水污染和环境噪音的影响。 在真空中，预计电磁力和清洁环境的检测将得到几个数量级的改进。 真空ANSOM将被开发并应用于半导体线/点发射间歇性、纳米级磁光克尔效应等。 该仪器的开发需要 UND 六个以上研究小组的合作。 将设计各种项目，以在整个项目期间积极吸引研究生、本科生、K12 学生和教师。 开发阶段完成后，该仪器将被安置在集中的 UND 综合成像设施中，更广泛的用户可以从其独特的功能中受益。

This Major Research Instrumentation award supports the University of Notre Dame (UND) with the development of a vacuum based apertureless near-field scanning optical (ANSOM) and magneto-optical Kerr effect microscope for nano-science applications. The instrument inherits the advantage of both atomic force microscopy and optical microscope, which are its two complementary parts. To date, there is no such system available from commercial vendors. Though ANSOM in air has been rather widely applied to investigate electronic and optical properties of nanoscale materials, it suffers from water contamination and noise from the ambient. In vacuum, a few orders of magnitude improvement in the detection of electrical and magnetic forces and a clean environment are expected. Vacuum ANSOM will be developed and applied to semiconductor wire/dot emission intermittency, nano-scale magneto-optical Kerr effects and more. This instrument development necessitates collaboration among more than six research groups at UND. Various projects will be designed to actively engage graduate students, undergraduate students, K12 students and teachers throughout the duration of the project. Upon completion of the development phase, the instrument will be housed in the centralized UND Integrated Imaging Facility, where a broader range of users can benefit from its unique capabilities.******This Major Research Instrumentation award supports the University of Notre Dame (UND) with the development of a vacuum based apertureless near-field scanning optical (ANSOM) and magneto-optical Kerr effect microscope for nano-science applications.
