Abstract

We have demonstrated the direct formation of elongated Ag particles with a quasi-parallel major axis on SiO2 template layer by using dynamic oblique deposition (DOD). The peculiar nanomorphology of the particles and template is physically self-organized owing to the self-shadowing in the oblique vacuum deposition. The resulting films exhibit anisotropic optical absorption due to plasma resonance sensitive to the shape of the Ag particles on the template. Since our method can be applied to any combination of thin film materials, it is useful for enabling the plasmon-mediated optical phenomena and to apply them for the development of various photonic devices such as thin film polarizers.
