Outline of Final Research Achievements

I investigated optimization of the condition of the electric assist self-assembly method to get the perpendicular oriented hexagonal mesoporous silica thin films with magnetic metal particles in the mesopore. A bias electric field and constant current mode on low-resistive Si substrate were effective in oriented mesopore. Co particles filled using a pulse-plating method were deposited on substrate, not inside the mesopore, because of irregular structures of initial film layer and low adhesion of films. I investigate continually about regularization of initial layer of films and the adhesion improvement of films.
