Nanoporous Films and Nanostructure Arrays Created by Selective Dissolution of Water-Soluble Materials.

ABSTRACT: Highly porous thin films and nanostructure arrays are created by a simple process of selective dissolution of a water-soluble material, Sr₃Al₂O₆. Heteroepitaxial nanocomposite films with self-separated phases of a target material and Sr₃Al₂O₆ are first prepared by physical vapor deposition. NiO, ZnO, and Ni_{1- x} Mg _x O are used as the target materials. Only the Sr₃Al₂O₆ phase in each nanocomposite film is selectively dissolved by dipping the film in water for 30 s at room temperature. This gentle and fast method minimizes damage to the remaining target materials and side reactions that can generate impurity phases. The morphologies and dimensions
