|Abstract:||Formation of metal oxide nanotubes by Kirkendall effect  through oxidation of the metal nanowire has been frequently reported for nanotubes of FeO, ZnO, AlO and CuO. One important material is nickel oxide (NiO) as it has desirable properties for use in gas sensing, non-volatile resistive switching memories and dye sensitized photocathodes [2, 3, 4]. Unfortunately, oxidation of Ni appears to be tricky and unique. Recently, attempts to oxidize Ni nanowires yields bamboo-like structures with separated voids and irregular diameters as opposed to the formation of uniformly thick walls that is common for CuO, FeO etc.  Understanding the oxidation behaviour of Ni nanowires is therefore important in aiding to understand the factors that influence the Kirkendall effect. In doing so, uniform NiO nanotubes that is important for reliability and reproducibility can possibly be produced. © 2010 IEEE.|
