Abstract

We have studied ferroelectric behaviour of barium titanate (BaTiO3) thin films prepared with sol-gel method. BaTiO3 solutions were deposited onto silicon substrates with different numbers of layers via spin coating method. The obtained samples were sintered at 700 °C and 800 °C. Structure and ferroelectric properties of the samples were investigated using X-ray diffraction (XRD) and Sawyer-Tower circuit. As observed from XRD patterns, number of layers affected the films structure. Results also showed that crystallographic system of BaTiO3 thin films was characterized by a tetragonal structure. Maximum polarization increased with an increase in layer number. Spontaneous polarization was also observed increasing with an increase in temperature.
