Lithographically defined microporous templates in conjunction with the atomic layer deposition (ALD) technique enable remarkable control of complex novel nested nanotube structures. So far three-dimensional physical process parameters has not been fully realized high precision resolution, and requires optimization order to achieve a wider range potential applications. Furthermore, combination composite insulating oxide layers alternating semiconducting metals can provide various types applications eventually unique advanced levels multifunctional nanoscale devices. Semiconducting TiO2 nanotubes have photovoltaic The nanostructured materials metal produce vertically-ordered nanodevices. Platinum growth by ALD explored, covering initial stages thin film nucleation synthesis aspect ratio penetration depth Pt into porous having pore sizes ratios investigated. Several multi-walled TiO2-Pt series successfully fabricated using Si templates. These innovative nanostructures nanodevices sensing technologies.
