Photoinduced Formation of Wrinkled Microstructures with Long‐Range Order in Thin Oxide Films

Abstract

Thin oxide films with long-range ordered microstructures were fabricated by a wrinkling process initiated by photopolymerization. The faster polymerization of the film surface generates a buckling effect to create patterns in the films. The removal of the organic polymer by thermal treatment leaves titania microstructures having long-range order. This method of producing micropatterned structures can find several applications in photonics.
