Abstract
|
Nanotechnology faces key challenges: minimizing material use, increasing efficiency, and ensuring stability. Tailored nano-engineering of colloidal metasurfaces via template-assisted self-assembly offers promising solutions to these challenges. Metasurfaces derive their unique properties from structured formations rather than constituent materials. This chapter explores the creation of functional metasurfaces using presynthesized nanoparticles, responsive polymers, and specifically designed templates. The nanostructuring of these templates effectively integrates both top-down and bottom-up lithography techniques. Top-down lithography allows the precise creation of arbitrary and repetitive templates, while bottom-up approaches will enable the formation of colloidal nanostructures through controlled solvent evaporation. We demonstrate that these approaches must be combined to exploit nanophotonic concepts fully for scalable manufacturing. Techniques such as laser interference and soft lithography are used to fabricate high-quality templates suitable for large-area self-assembly of optoelectronic properties. This chapter also illustrates the targeted optimization of optoelectronic properties for sensing, energy, and spectroscopy applications.
