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

该主要研究仪器奖支持圣母大学（UND）开发用于纳米科学应用的真空无孔近场扫描光学（ANSOM）和磁光克尔效应显微镜。仪器继承了原子力显微镜和光学显微镜的优点，两者互为补充。到目前为止，还没有商业供应商提供这样的系统。尽管空气中的ANSOM已被广泛应用于研究纳米材料的电子和光学性质，但它受到水污染和环境噪声的影响。在真空中，电磁力的检测和清洁的环境有望有几个数量级的改进。真空ANSOM将被开发并应用于半导体线/点发射间歇、纳米尺度磁光克尔效应等领域。这种仪器的发展需要开发计划署六个以上的研究小组进行合作。在整个项目期间，将设计各种项目，以积极吸引研究生，本科生，K12学生和教师。在开发阶段完成后，该仪器将被安置在联合开发计划署的中央综合成像设施中，在那里，更广泛的用户可以从其独特的能力中受益。******该主要研究仪器奖支持圣母大学（UND）开发用于纳米科学应用的真空无孔近场扫描光学（ANSOM）和磁光克尔效应显微镜。仪器继承了原子力显微镜和光学显微镜的优点，两者互为补充。到目前为止，还没有商业供应商提供这样的系统。尽管空气中的ANSOM已被广泛应用于研究纳米材料的电子和光学性质，但它受到水污染和环境噪声的影响。在真空中，电磁力的检测和清洁的环境有望有几个数量级的改进。真空ANSOM将被开发并应用于半导体线/点发射间歇、纳米尺度磁光克尔效应等领域。这种仪器的发展需要开发计划署六个以上的研究小组进行合作。在整个项目期间，将设计各种项目，以积极吸引研究生，本科生，K12学生和教师。在开发阶段完成后，该仪器将被安置在联合开发计划署的中央综合成像设施中，在那里，更广泛的用户可以从其独特的能力中受益。

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.
