| Research Abstract |
The structures containing 2D and 3D ordering of nano/micrometer-sized monodisperse particles have several key applications in materials science and engineering. The study on the geometrical packing / arrangement of such particles has been growing to one of the most attractive research fields in recent years. In order to overcome various a difficulty in conventional studies, novel technique to fabricate 2D close-packed structures was developed in this study. It was effective to apply the superimposed electric field to solvent-suspended monodisperse silica particles on a substrate for fabricating the close-packed structure. Formation mechanisms and processes of ordered structure were also discussed in this study.
