High Aspect‐Ratio Cylindrical Nanopore Arrays and Their Use for Templating Titania Nanoposts

Abstract

Well-defined arrays of titania nanoposts are generated by using high aspect-ratio cylindrical nanopore templates. The simple and controllable fabrication scheme of the nanoporous templates makes them very attractive for creating well-defined nanostructures out of a variety of functional materials. The arrays of titania nanoposts can find a variety of applications such as photonic crystals, photocatalysts, and photovoltaics.
