Recently, metal nanostructures such as meta-material attract many scientists because it enables us to develop optical technology. Simple and high-productive fabrication using self-assembly of dielectric particles is a promising approach for this objective. In this research field, the existence of defects in the nanostructures and the unavoidable influence of the dielectric material on optical characteristics are major problems. Here, we focus on and the difference of interfacial energy at dielectric/metal interface to solve these problems.
