Multilayered Domain Control for Surface Plasmon Resonance

Abstract

Metal particles are utilized to study surface plasmon resonance. They are regulated in terms of their dimensions to control surface plasmon resonance, and sealed with a dielectric material. In this study, we applied a method of domain growth to form particles. It is an advantage in manufacturing because the entire process is carried out in a sputtering system. We describe a method of multilayered domain control (MLDC), illustrating it with Au, Ag and Cu for particles and SiO₂ for dielectric layers in this paper. A remarkable feature of MLDC is its intensification of surface plasmon resonance. Moreover, this intensification enables base metals to substitute for noble metals.
