    We have fabricated ordered convex and concave arrays in metallic layers which were controlled by altering the temperature of the solutions during processing. A cationic polymer layer containing a palladium catalyst was formed over the air pockets in a porous polymer film template. A metallic layer was formed from the cationic polymer layer by electroless plating. The temperature of the aqueous cationic polymer solution and the plating bath solution controlled the thermal expansion and shrinkage of the polymer film. An ordered metallic layer was not obtained when the polymer and bath solutions were at the same temperature, and the interface remained flat. When the polymer-catalyst solution was warmer than the plating bath solution, convex metallic arrays were formed, and when the polymer-catalyst solution was cooler, concave arrays were formed. These results demonstrate the feasibility of using air pocket arrays as a template for ordered nanoscale metallic arrays.
