U.S.-Germany Cooperative Research: Stresses and Deformation Mechanisms in Thin Metal Films

9815702贝克该奖项支持PI，Shefford Baker和两名研究生与德国斯图加特马克斯普朗克金属科学和金相研究所的Eduard Arzt合作。 研究重点是金属薄膜的变形机制，以了解此类薄膜所特有的机械行为的微观结构起源。 该支持将允许研究生在PI的监督下，花时间在马克斯普朗克研究所进行研究，作为他们博士学位的一部分。工作 一个项目将研究非常不寻常的机械行为，这似乎是由于显着的可逆塑性变形，取决于薄铜膜中的氧含量。 另一个项目将研究弹性各向异性对薄金属膜二维晶粒结构中不同取向晶粒的变形机制的影响。 本研究中所研究的金属薄膜在集成电路、微机械元件、光学涂层等技术应用中具有越来越重要的意义。

9815702BakerThis award supports the PI, Shefford Baker, and two graduate students in a cooperation with Eduard Arzt of the Max Planck Institute for Metals Science and Metallography in Stuttgart, Germany. The research focus is on the deformation mechanisms in thin metal films in order to understand the microstructural origins of mechanical behavior which is unique to such films. The support will allow the graduate students, under the supervision of the PI, to spend time doing research at the Max Planck Institute as part of their Ph.D. work. One project will investigate very unusual mechanical behavior which appears to result from significant reversible plastic deformation that depends on oxygen content in thin copper films. The other project will study the effects of elastic anisotropy on deformation mechanisms in grains of different orientations in the two-dimensional grain structure of a thin metal film. The thin metal films being studied in this research are of increasing importance in technological applications such as integrated circuits, micromechanical components, optical coatings, and others.
