U.S.-Japan Dissertation Enhancement in Advanced X-ray Scattering Techniques for Complex Oxides

该奖项支持博士学位。PI实验室的一名学生前往日本播磨的Spring-8同步辐射设施，参与复杂氧化物材料同步加速器X射线散射探针的合作开发。开发先进X射线技术的研究人员是国际性的，依赖于广泛分布的团体之间的合作。该奖项支持与由Osami Sakata和Shigeru Kimura博士领导的Spring-8研究人员合作开发和应用一系列复杂氧化物的新表征技术。在过去的几年里，Spring-8团队在X射线散射方面展示了令人印象深刻的创新，包括确定外延纳米结构和薄膜结构的技术进步。在设计和理解复杂氧化物材料方面也取得了相应的进展，创造了一系列新的机会。与Spring-8小组的合作将探测铁性复合氧化物薄膜中的两种相关现象。该学生和美国团队的其他成员将使用界面衍射技术研究外延铁电电容器的两种相反极化状态的结构。第二项工作将使用相关技术来探测多铁性复合氧化物薄膜的磁性。这种合作的目的是立即有助于学生的博士论文，并成为学生毕业后未来工作的重要技术和个人基础。这项合作将产生更广泛的影响，有助于解决长期存在的关于复杂氧化物薄膜的极化和磁性的科学问题，并将成为PI小组未来工作的基础。除了传播我们合作的科学成果外，PI还计划以各种方式传达国际合作的其他好处。合作的结果将纳入PI教授的课程和PI小组所有成员参与的外联活动。

This award supports a Ph.D. student from the PI's lab to travel to the Spring-8 synchrotron radiation facility in Harima, Japan to participate in collaborative development of synchrotron x-ray scattering probes for complex oxide materials. The community of researchers developing advanced x-ray techniques is international and depends on cooperation between widely distributed groups. The award supports development and application of a series of new characterization techniques for complex oxides in collaboration with researchers at Spring-8, led by Drs. Osami Sakata and Shigeru Kimura. Over the past few years, the Spring-8 team has demonstrated an impressive number of innovations in x-ray scattering, including advances in techniques for determining the structure of epitaxial nanostructures and thin films. Commensurate advances in the design and understanding complex oxide materials have also occurred, creating an array of new opportunities. The collaboration with the Spring-8 group will probe two related phenomena in ferroic complex oxide thin films. The student and others on the U.S. team will use interface diffraction techniques to study the structure of the two opposite polarization states of epitaxial ferroelectric capacitors. A second effort will use related techniques to probe the magnetism of multiferroic complex oxide thin films. This collaboration is designed both to contribute immediately to the student's PhD thesis and to be an important technical and personal foundation for future work after the student's graduation. This collaboration will have broader impact in contributing to resolving longstanding scientific problems regarding the polarization and magnetism of complex oxide thin films and will form the basis for future work in the PI's group. In addition to disseminating the scientific results of our collaboration, The PI plans to communicate the other benefits of international collaboration in a variety of ways. Results from the collaboration will be incorporated into courses taught by the PI and into outreach activities involving all of the members of the PI's group.
