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

这一重大研究仪器奖支持圣母大学(UND)开发基于真空的无孔近场扫描光学(ANSOM)和用于纳米科学应用的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，是它的两个互补部分。到目前为止，还没有商业供应商提供这样的系统。虽然空气中的ANSOM已被广泛应用于研究纳米材料的电学和光学性质，但它受到水的污染和环境噪声的影响。在真空中，预计在电磁和磁力的检测和清洁环境方面将有几个数量级的改进。真空ANSOM将被开发并应用于半导体线/点发射的间歇性、纳米尺度的磁光克尔效应等方面。这一工具的开发需要联合国开发计划署的六个以上研究小组之间的合作。将设计各种项目，以便在整个项目期间积极参与研究生、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UND中央综合成像设施中，在那里更多的用户可以从其独特的能力中受益。*这一重大研究仪器奖支持圣母大学(UND)为纳米科学应用开发基于真空的无孔近场扫描光学(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，是它的两个互补部分。到目前为止，还没有商业供应商提供这样的系统。虽然空气中的ANSOM已被广泛应用于研究纳米材料的电学和光学性质，但它受到水的污染和环境噪声的影响。在真空中，预计在电磁和磁力的检测和清洁环境方面将有几个数量级的改进。真空ANSOM将被开发并应用于半导体线/点发射的间歇性、纳米尺度的磁光克尔效应等方面。这一工具的开发需要联合国开发计划署的六个以上研究小组之间的合作。将设计各种项目，以便在整个项目期间积极参与研究生、本科生、K12学生和教师。在开发阶段完成后，该仪器将存放在联合国开发计划署集中的综合成像设施中，在那里，更多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.
