Abstract: Highly oriented Ba(Zr0.2Ti0.8)O3 thin films are grown on(001) SrTiO3∶ω(Nb)=1.0 % single crystal substrates using pulsed laser deposition and the dielectric properties of the films are evaluated.The thin films are in situ annealed at 650 ℃ for 10 min.and the highly(001)-oriented BZT thin films are obtained.The structure and surface morphology of the films have been characterized by X-ray diffraction(XRD) and atomic force microscopy(AFM).XRD and AFM characterization reveal a good crystallinity:the...
