0.935Bi1/2Na1/2TiO3-0.065BaTiO3-0.01Al6Bi2O12 (BNT-BT-AB) thin films were prepared via pulse laser deposition (PLD) on the substrates of Pt(111)/Ti/SiO2/Si (Pt) and LaNiO3 buffered Pt (111)/Ti/SiO2/Si (LNO/Pt), respectively. The morphology structure and electric properties of the films were investigated by X-ray diffraction, scanning electron microscopy, atomic force microscopy and ferroelectric analysis. The results show that the BNT-BT-AB film deposited on Pt exhibits a random orientation, the morphology of grain is cubic, the remnant polarization 2Pr is 20.38 μC/cm2, the dielectric tunability is 19% and the piezoelectric coefficient d33* is 130 pm/V. The BNT-BT-AB film deposited on LNO/Pt has a (100) preferred orientation, the surface morphology is flat, the residual polarization 2Pr is 21.25 μC/cm2, and the dielectric constant (700) and dielectric tenability (23%) are greater than those of the BNT-BT-AB film deposited on Pt, and the enhanced piezoelectric coefficient d33* is 150 pm/V.
