0233283BakerThis three-year award for US-France collaboration in materials research involves researchers and students at the Cornell University and the University of Aix-Marseilles. Shefford P. Baker in the US and Olivier Thomas in France lead this collaboration. They will investigate stress distribution in nanofabricated metal structures. They will also determine the effects on mechanical behavior and reliability. This work will be accomplished by a combination of high-resolution x-ray diffraction experiments at the Cornell High Energy Synchrotron Source. Samples will include model single and bi-crystal thin film systems, polycrystalline films, and nanofabricated line arrays. The French investigators will focus on x-ray data analysis and modeling of x-ray spectra and the US investigators will contribute sample preparation and mechanical modeling. Both groups will participate in the design and execution of x-ray measurements at the Cornell High Energy Synchrotron Source. Research on metal films and nanostructures at the 10-1000 nanometers play critical roles in virtually all nanofabricated devices. The result of this collaboration will advance understanding of the mechanical behavior of thin metal films and nanopatterned structures, which will be of value in industries that rely on nanofabrication.This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US investigator and his students. The CNRS will support visits by French researchers and students to the United States.

这个为期三年的美法材料研究合作奖涉及康奈尔大学和艾克斯-马赛大学的研究人员和学生。美国的Shefford P.Baker和法国的Olivier Thomas领导了这一合作。他们将研究纳米复合材料金属结构中的应力分布。它们还将确定对机械性能和可靠性的影响。这项工作将由康奈尔高能同步加速器源的高分辨率X射线衍射实验相结合来完成。样品将包括模型单晶和双晶薄膜系统、多晶薄膜和纳米硬化线阵列。法国调查人员将专注于X射线数据分析和X射线光谱建模，美国调查人员将负责样品准备和机械建模。这两个小组都将参与康奈尔高能同步加速器源X射线测量的设计和执行。对10-1000纳米的金属薄膜和纳米结构的研究在几乎所有的纳米器件中都扮演着关键的角色。这一合作的结果将促进对金属薄膜和纳米晶化结构的机械行为的理解，这将在依赖纳米制造的行业中具有价值。该奖项代表了美国方面向NSF和CNRS提出的平行建议。NSF将支付这名美国调查员和他的学生的旅费和生活费。CNRS将支持法国研究人员和学生访问美国。
