Fabricating Ordered Voids in a Colloidal Crystal Film–Substrate System by Using Organic Liquid Patterns as Templates



A colloidal crystal film–substrate system with ordered voids has been fabricated using a combination of microcontact printing, self-organization of organic liquid on the patterned self-assembled monolayers, and a vertical deposition technique. The Figure shows an SEM image of the bottom surface of a colloidal crystal film that had been peeled off the substrate after the solvent has evaporated.
