Synthesis,Characterization and Electrical Properties of Barium Titanate Films Fabricated by Hydrothermal Method

摘要：

　　BaTiO3 films with a thickness up to 3 μm were fabricated under the hydrothermal conditions.It was found that the crystallinity of BaTiO3 increases with the concentration of Ba(OH)2 solutions.Along with the increasing of time,the crystallinity of BaTiO3 increases,reaches the maximum value and then decreases.The measured values of remanent polarization (Pr) and coercive field (Ec) are 1.74pC/cm2 and 24KV/cm.The leakage of the films at 1V is 10-7m/cm2.The dielectric constant and loss tangent of hydrothermal derived BaTiO3 film at a frequency of 1 KHz were 600 and 0.2,respectively.
