Abstract :
We have theoretically investigated the oriented growth of ferroelectric thin films on substrates without lattice match by applying a low electric field during deposition. Several kinds of electrode geometry were proposed. The growth mechanism was interpreted in accordance with the electrostatic energy of ferroelectrics in electric field and compared with the poling of polycrystalline ceramics. Two criterions were derived to select ferroelectrics suiting low electric field induced oriented growth
