Bi2WO6 films were deposited by metalorganic chemical vapor deposition for the first time. The perfect epitaxially grown (001)-oriented films were deposited on (100)LaAlO3, (100)SrTiO3 and (100)CaRuO3//(100)SrTiO3 substrates at 500°C. However, the perfect (001)-oriented film was not deposited on a (100)CaRuO3//(100)SrTiO3 substrate when the deposition temperature decreased to 400°C. Ferroelectricity was observed only for the film deposited on the (100)CaRuO3//(100)SrTiO3 substrate at 600°C. The doubled remanent polarization and the coercive field of the film were 0.17 μC/cm2 and 7.0 kV/cm, respectively.
