A new synthetic method is reported for depositing BaTiO3 nanowire film on conducting glass. First, a TiO2 particle thin film is prepared by spray coating, and then transformed to single crystalline BaTiO3 nanowires grown on the conducting glass by hydrothermal treatment using TiO2 particles as seeds of nanowire growth. The BaTiO3 nanowires are 50-100 nm in diameter and have a film thickness of 4 mu m. The capacitance of the BaTiO3 one-dimensional (1D) nanowire array film was found to be 4.5 times higher than that of the nanoparticle film by measuring the impedance. The piezoelectric property of an individual BaTiO3 nanowire was also demonstrated by piezoforce microscopy.
