Abstract
In this talk, I will describe a novel fabrication method based on DNA-assembly of gold nanoparticles on a substrate, which can be used to design passive and active nanophotonic metamaterials and metasurfaces. In particular, we have demonstrated wide range of functional nanophotonic device architectures including epsilon-near-zero metasurfaces, negative index metamaterials and broadband absorber metafilms. The synthesis of plasmonic NP architectures with structures and stimuli-responsive behavior that are not accessible in lithographically-defined plasmonic nanostructures provides an opportunity to design materials with emergent optical properties that offer new fundamental insights and previously inaccessible functionalities.
