Hydrothermal synthesis of vertically aligned lead zirconate titanate nanowire arrays

Ahydrothermal method is employed for the growth of single crystal vertically aligned lead zirconate titanate (PZT) nanowire arrays. The resulting PZT nanowires were grown from a TiO2 film and are shown to be single crystal with growth in the [110] axis. PZT has a coupling coefficient up to two orders of magnitude higher than ZnO, which should provide many opportunities for the creation of active nanodevices and systems.
