Abstract:
A process for forming a metal particle ordered structure on a substrate, comprising the steps of:(1) immersing a metal oxide film substrate in a solution containing at least APTS (3-(2-amino-ethylamino)propyltrimethoxysilane) to form a self-aligning membrane (SAM) of APTS on the substrate surface; (2) immersing the substrate with the SAM in a solution containing metal particle colloid with a particle size (D) of 0.8&lE;D&lE;10 nm to load metal colloids on the SAM surface; (3) immersing the substrate on whose SAM surface metal colloids are loaded in a solution containing at least a material having a thiol group to thiolate the metal particles for providing metal thiol particles; and (4) applying a voltage between the substrate where metal colloids are loaded on the SAM surface as a first electrode and a second electrode in the solution while conducting the above step (3).
