Fabrication of TiO<inf>2</inf> nanowire arrays using laser interference lithography aided hydrothermal method

Abstract

Titanium dioxide (TiO 2 ) is one of the most widely investigated semiconductor materials because of its unique properties. TiO 2 nanowire arrays can be synthesized through a two-step method, the fluorine-doped tin oxide (FTO) substrates were ablated using laser interference lithography technology, and TiO 2 nanowire arrays were grown on the patterned FTO substrates. The TiO 2 nanowire arrays were characterized by SEM and XRD measurements. This work provides a high efficient method for the fabrication of ordered TiO 2 nanowire arrays for different applications in highly functionalized assemblies and composites.
