Reliable metal deposition into TiO2 nanotubes for leakage-free interdigitated electrode structures and use as a memristive electrode

Abstract

Nearly 100 % filling of TiO2 nanotubes with metals, including Ag, Cu, Au, and Pt, was achieved by defect-sealing treatment at the bottom of the nanotubes, followed by metal deposition using nuclei formation/coalescence. The resulting short-circuit-free interdigitated electrode configurations can, for example, be used to fabricate memristive electrodes. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
