Fabrication of Particle Assembly by Using Electrophoretic Deposition Process

Microdots and Micropatterns Consisting of Colloidal Crystal

Abstract

Microfabrication processes for particle arrangement is very important in developing micrometerscaled materials or devices with a high performance. It is especially well known that a three-dimensional ordering of monodisperse microspheres gives optical characteristics for future photonic application such as optical waveguide, laser oscillation, and sensor. Microdots and micropatterns consisting of three-dimensionally ordered monodisperse microspheres of polymer or ceramics were fabricated by using electrophoretic deposition process with a microelectrode or a patterned electrode.
