Stacked Split Ring Resonators Driven by Pagoda-like nanostructure for optical metamaterials |
| 초록 |
We realized stacked split ring resonators from “pagoda-like” nanorods over a large area (~cm2) exhibiting polarization difference in near-infrared (NIR) wavelengths. This array of “pagoda-like” nanorods was fabricated by confining lamellar-forming polystyrene-block-poly (methyl methacrylate) copolymer (PS-b-PMMA) inside cylindrical pores of aluminum oxide (AAO) template grafted by thin neutral brush layers. PS and PMMA lamellar nanodomains with the sizes of ~70 nm were alternatively stacked along the nanorod direction. After the AAO template was removed, “pagoda-like” nanorods generated by O2 reactive ion etching. Stacked split ring resonators exhibits optical polarization difference, followed by tilt gold deposition on the nanorods. This concept of fabricating sophisticated nanoscale architectures by utilizing block copolymer self-assembly and incorporating plasmonic metals could be applied to realize large-scale metamaterials working at visible and NIR wavelengths. |
