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.

9815702Baker 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与金相研究所的 Eduard Arzt 合作。 研究重点是金属薄膜的变形机制，以了解此类薄膜独特的机械行为的微观结构起源。 这项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，作为其博士学位的一部分。工作。 一个项目将研究非常不寻常的机械行为，这种机械行为似乎是由取决于薄铜膜中的氧含量的显着可逆塑性变形引起的。 另一个项目将研究弹性各向异性对金属薄膜二维晶粒结构中不同取向晶粒变形机制的影响。 本研究中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变得越来越重要。
