Abstract By reducing the layer thickness, h, in metal multilayers from micrometer- to nanometer-levels, scale-dependent transitions in behavior are observed. The role of interface properties in these transitions has been extensively investigated. However, reducing h to the nanoscale regime also imposes a physical geometric confinement on defect-related processes occurring within the layers, an effect that is less explored. We present illustrative examples of the influence of nanoconfinement on the strength, structure, and radiation response of multilayers. These examples show that nanoconfinement and interface structure and topology act cooperatively in the nanoscale limit, affecting behaviors that cannot be explained based on either factor alone.

纳米尺度限制对金属层压板行为的影响

摘要 通过将多层金属中的层厚度 h 从微米级降低到纳米级，可以观察到行为中与尺度相关的转变。界面特性在这些转变中的作用已被广泛研究。然而，将 h 减少到纳米级范围也会对层内发生的与缺陷相关的过程施加物理几何限制，这种影响很少被探索。我们展示了纳米限制对多层结构的强度、结构和辐射响应的影响的示例。这些例子表明，纳米限制和界面结构和拓扑在纳米尺度范围内协同作用，影响无法单独基于任一因素解释的行为。
