Layer-in-Layer Hierarchical Nanostructures Fabricated by Combining Holographic Polymerization and Block Copolymer Self-Assembly
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 {approx}200 nm in thickness, confining a block copolymer (BCP) to {approx}100 nm domains. Subsequently, the BCP self-assembles into nanolayers with a period of {approx}21 nm. We envisage that this approach opens a gateway to fabricating hierarchical nanostructures at different length scales.
