Abstract
The creation of new advanced functional materials is anticipated by assembling micrometer-sized particles which have various kinds of functions. In this work, a new concept for assembling powder particles is proposed, and preliminary research results of this assembling are reported. The process for assembling is as follows; (1) electrified patterns are drawn on calcium titanate substrate using electron beam drawing and observed by the voltage contrast method, (2) the substrates are dipped into solvent in which spherical silica particles (5μm in diameter) are dispersed, and (3) the particles are adhered to the electrified patterns under suitable conditions. The amounts of adhered particles are influenced by the density of particles in the solvent, the dose electron density of electrification and dipping time of the substrate into the solvent. By using adequate values of these parameters, comparatively clear silica particle arrangements on the electrified patterns were obtained.
