A mosaic consisting of pillars of two kinds of metal, gold and nickel, has been deposited on porous alumina substrates. A sequence of barrier layer application, selective penetration of the barrier, and metal deposition can be manipulated to control the arrangement and density of the composites. An array of Au (brighter) and Ni cylinders is shown in the Figure.
