We report the combination of top-down and bottom-up nanomanufacturing techniques to fabricate active, hierarchically structured volume reflection gratings. Holographic polymerization (H-P) formed lamellar structures of approximately 200 nm in thickness, confining a block copolymer (BCP) to approximately 100 nm domains. Subsequently, the BCP self-assembles into nanolayers with a period of approximately 21 nm. We envisage that this approach opens a gateway to fabricating hierarchical nanostructures at different length scales.
我们报告了自上而下和自下而上的纳米制造技术相结合的方法，以制造具有活性的、层次结构的体反射光栅。全息聚合（H-P）形成了厚度约为200nm的层状结构，将嵌段共聚物（BCP）限制在约100nm的区域内。随后，BCP自组装成周期约为21nm的纳米层。我们设想这种方法为在不同长度尺度上制造层次纳米结构打开了一扇大门。
