제목 Template-Assisted Fabrication of Highly Ordered Freestanding Titanium Oxide Nanotube Arrays via Si-Containing Block Copolymer Lithography and Atomic Layer Deposition.
초록 Highly ordered freestanding TiO2 nanotube arrays with various wall thicknesses were fabricated by applying atomic layer deposition (ALD) to the nanoporous templates with high aspect ratios. The high thermal stability of the cross-linked organic template allowed high-temperature ALD. Easy removal of the organic template by a dry etch process followed by calcination produced vertically aligned and highly crystalline anatase TiO2 nanotube arrays without collapse or bundling. Furthermore, the ultrafine thickness tunability of the ALD process made it possible to develop TiO2 nanorods as well as nanotubes with different wall thicknesses. In addition, freestanding nanotube arrays were manufactured from TiO2-based multi-component films of TiO2/Al2O3/TiO2 nanolaminates and Ti-Al-O mixed-phase films.
