Antireflection: Fabrication of Periodic Nanostructure Assemblies by Interfacial Energy Driven Colloidal Lithography (Adv. Funct. Mater. 29/2014)

An interfacial energy-driven colloidal lithography technique to fabricate periodic nanostructure ensembles from a solution phase is demonstrated by A. Dev et al. on page 4577. It exploits different interfacial forces to periodically trap a liquid precursor under a monolayer of colloidal silica spheres arranged on a Si substrate. Using this technique, circular and ring-shaped patterns of ZnO nanowire ensembles and thin films are fabricated. The method described here can be adopted to make periodic patterns from a wide variety of soluble materials.
