Functional Materials Fabricated via Self-Organized Process

Abstract

This paper introduces the preparation and applications of self-assembled particle structures as an essay contributed in celebration of receiving the SJWS Promising Scientist Award in 2005. The author has worked on the self-organized structures of submicron-sized particles and made their widespread applications. Those structures were investigated as a model structure for the theoretical study of photonic crystals (a photonic crystal is a periodic structure in optical wavelength scale. They can control photons as a semiconductor does on electrons), and a template or a mask to prepare other functional structures. As the results, a photoelectrochemical micro-beaker, a diamond electron emitter, and a dye-sensitized photonic-crystal solar cell had been prepared.
