Ordered arrays of nanopillars formed by photoelectrochemical etching on directly imprinted TiO2 single crystals
Arrays of TiO2 nanopillars have been prepared by photochemically etching a TiO2 single crystal that had been previously imprinted with a corresponding array of dimples using SiC molds. The pillars have a high aspect ratio (see scanning electron microscopy (SEM) image in Figure) and the method is simple and suitable for high-throughput production.
