Theoretical and Experimental Investigation of Templates Designed for Block Copolymer Self-assembly into Spiral Morphology |
| 초록 |
Precise control of subwavelength-scale plasmonic nanostructures have emerged as substantial fields of research. Archimedean spirals, in particular, have shown unique and promising properties based on the asymmetric and complex nature of the structure. High-resolution patterning tools have been used to produce such complex nanostructure so far. However, these methods are often too slow and costly for large-scale productions and thus call for alternative approaches. Here, we report a novel, all bottom-up fabrication process for an asymmetric template designed to induce block copolymers self-assembly into spirals. Self-consistent field theoretic (SCFT) simulation has verified the thesis. Moreover, a simple alteration in the fabrication allows the handedness of the spirals to be controlled. This cost-effective and scalable alternative produces Archimedean spirals with high yield and high handedness selectivity. The nanoscale spirals were analyzed for potential applications in plasmonics. |
