Abstract

Pb(Zr,Ti)O3/BiFeO3/(PZT/BFO) multilayer thin films were coated on Pt/Ti/SiO2/Si substrates by chemical solution deposition. With increasing the annealing temperature, the dielectric and leakage current density properties of multilayered PZT/BFO/PZT thin films were improved. The current density of the PZT/BFO/PZT filmannealing at $600^{\circ}C$ was about 189.39(x10-9A/cm2) at 10V. The relative dielectric constant and the dielectric loss of the PZT/BFO/PZT thin film annealing at $600^{\circ}C$ were about 318 and 0.161%, respectively.
