Reliable Metal Deposition into TiO2 Nanotubes for Leakage-Free Interdigitated Electrode Structures and Use as a Memristive Electrode

摘要

Over the past decades, electrodeposition into ordered nano-porous, nanochanneled, or nanotubular substrates has been widely explored and exploited. In this regard, the use of ordered oxide or polymer membranes with pore diameters in the nanometer range as a template for the fabrication of metal or semiconductor nanowires or nanotubes (NTs) is most straightforward. In these cases, deposition is mostly followed by a selective dissolution of the template to obtain a freestanding array of the ID material of interest. Such attempts were pioneered by the groups of Uosaki, Martin, Masuda, Moskovits, and Gosele, who mostly used self-organized porous alumina or track-etched polycarbonate membranes as templates.
