This Major Research Instrumentation award supports Cornell University with the development of a unique optical microscope that can ?see? nanoscale features due to contrast in light reflection, absorption and emission in the far infrared as well as deep ultraviolet. This microscope achieves the high spatial resolution using a scanning probe of a nanometer scale and the greatly augmented optical field near this probe. It achieves high fidelity data with desired signal-noise ratio by locating the key components inside a vacuum environment. During the stage of its development, various research groups contributes to its design and testing by imaging a variety of semiconducting and multifunctional samples, which will also involve undergraduate students, K-12 students and teachers. Upon completion, the instrument will be made available to all interested users. ******This Major Research Instrumentation award supports Cornell University 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 an NSOM and a vacuum platform. Other critical features that set it apart from commercially available systems include its super broadband optical range as well as a wide window of temperature control. ANSOM in air has been rather widely applied to investigate electronic and optical properties of nanoscale materials, however, 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, polariton science and lasing, nano-scale magneto-optical Kerr effects and more. This instrument development necessitates collaboration among multiple research groups at Cornell University. 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 made available through a shared facilities platform, where a broader range of users can benefit from its unique capabilities.

这项主要的研究仪器奖通过开发了可以看到的独特光学显微镜的发展支持康奈尔大学。纳米级特征是由于光反射，吸收和发射的对比度以及深紫外线的对比。该显微镜使用纳米尺度的扫描探针和该探针附近的大量增强光场实现了高空间分辨率。它通过在真空环境中定位关键组件来实现具有所需信号比率的高忠诚数据。在开发的阶段，各个研究小组通过对各种半导体和多功能样本进行成像，为其设计和测试做出了贡献，这也将涉及本科生，K-12学生和老师。完成后，将向所有感兴趣的用户提供该仪器。 ******这项主要的研究仪器奖为康奈尔大学提供了基于真空的无磁场近场扫描光学（ANSOM）和磁光kerr效应显微镜的开发，用于纳米科学应用。该仪器继承了NSOM和真空平台的优势。将其与市售系统区分开来的其他关键功能包括其超级宽带光学范围以及温度控制的广泛窗口。空气中的ANSOM已被广泛应用于研究纳米级材料的电子和光学性质，但是，它遭受了环境的水污染和噪声。在真空中，预计电气和磁力的检测以及清洁环境的检测方面有几个数量级的改善。 Vacuum Ansom将开发并应用于半导体线/点发射间歇性，Polariton Science and Lasing，纳米尺度磁光 - 光学KERR效应等等。这种工具开发需要在康奈尔大学的多个研究小组之间进行合作。在整个项目期间，各种项目将旨在积极吸引研究生，本科生，K12学生和老师。开发阶段完成后，该仪器将通过共享设施平台提供，在该平台中，更广泛的用户可以从其独特的功能中受益。
