چکیده انگلیسی
Fibre-textured and epitaxial Nb-doped Pb(Zr0.53Ti0.47)O3 (PNZT) thin films were grown on the different substrates by a sol-gel process. The [1Â 0Â 0]- and [1Â 1Â 1]-fibre-textured polycrystalline PNZT films were obtained on platinized silicon substrates by introducing PbO and TiO2 seeding layers, while the [0Â 0Â 1]- and [1Â 1Â 1]-oriented epitaxial PNZT films were formed directly on Nb-doped SrTiO3 (Nb:STO) single-crystal substrates with (1Â 0Â 0) and (1Â 1Â 1) surfaces, respectively. The preferential orientation and phase structure of the fibre-textured and epitaxial PNZT films, as well as their influences on the electrical properties were investigated. Higher remnant polarization (Pr) and piezoelectric coefficient (d33) were obtained for the epitaxial PNZT films on Nb:STO substrates than that for the fibre-textured ones on platinized silicon substrates. For both fibre-textured and epitaxial cases, the PNZT films with [1Â 0Â 0]/[0Â 0Â 1] orientations show higher piezoelectric responses than [1Â 1Â 1]-oriented ones, whereas better ferroelectric properties can be obtained in the latter. The intrinsic and extrinsic contributions were discussed to explain the difference in electrical properties for differently oriented fibre-textured and epitaxial PNZT films on different substrates.
