MRI: Development of Combined Optically-pumped and Optically-detected NMR of Bulk and Nanostructured Semiconductors

该奖项是根据2009年《美国复苏和再投资法案》(Public Law 111-5)获得的。在重大研究仪器(MRI)项目的这一奖项的资助下，来自华盛顿大学圣路易斯分校的索菲娅·海斯和她的研究小组将开发一种能够光泵和光学检测的核磁共振(核磁共振)测量的仪器。该仪器将光抽运核磁共振技术和光学检测核磁共振技术结合在一起，成为一种独一无二的仪器。该光谱仪将用于研究块体和纳米结构半导体材料。这些材料具有许多重要的光电性质，即将开展的研究可以直接探测缺陷或陷阱位，并研究这些位对重要物理性质的影响，如载流子动力学。该项目将由不同的年轻科学家群体进行，包括本科生和研究生。这项研究还包括与国际(德国多特蒙德大学)和工业研究伙伴(Kopin Coropation和MEMC)的重要合作，进一步扩大了这项研究的影响。新型核磁共振技术开辟了新的研究途径。利用该奖项开发的仪器将使科学家能够以前所未有的灵敏度研究重要材料的性质。该仪器将是此类仪器中的第一台，将使海耶斯、她的学生和合作者能够探索具有重要技术意义的材料的性质。此外，参与该项目的研究学生将接受跨学科教育，并获得参与国际和行业合作的额外好处，这将为他们在科学和技术领域的成功职业生涯做好准备。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program, Sophia Hayes and her research group from Washington University - St. Louis will develop an instrument capable of optically-pumped and optically-detected nuclear magnetic resonance (NMR) measurements. The proposed instrument will combine the techniques of optically-pumped NMR and optically-detected NMR into a one-of-a-kind instrument. The proposed spectrometer will be used to study bulk and nano-structured semi-conductor materials. These materials have a number of important optoelectronic properties, and the studies that will be carried out can directly probe defect or trap sites, and study the impact of these sites on important physical properties, such as carrier dynamics. The project will be carried out by a diverse group of young scientists, including undergraduate and graduate students. The research also features important collaborations with international (University of Dortmund, Germany) and industrial research partners (Kopin Coroporation and MEMC), further broadening the impact of this research.New kinds of NMR techniques open up new avenues of research. The instrument developed with this award will allow scientists to study the properties of important materials, with unprecedented sensitivity. The instrument will be the first of its kind, and will enable Hayes, her research students and collaborators to probe the properties of technologically important materials. In addition, the research students working on this project will receive an interdisciplinary education, with the added benefits of exposure to international and industrial collaborations, which will prepare them for successful careers in science and technology.
