Title: Long-range stripe nanodomains in epitaxial (110) BiFeO 3 thin films on (100) NdGaO 3 substrate

Abstract

Here, we report the observation of ferroelectric and ferroelastic nanodomains in (110)-oriented BiFeO 3 (BFO) thin films epitaxially grown on low symmetric (100) NdGaO 3 (NGO) substrate. We observed long range ordering of ferroelectric 109° stripe nanodomains separated by periodic vertical domain walls in as-grown 130 nm thick BFO films. The effect of La 0.67Sr 0.33CoO 3 (LSCO) conducting interlayer on domain configurations in BFO/NGO film was also observed with relatively short range-ordering of stripe domains due to the modified electrostatic boundary conditions in BFO/LSCO/NGO film. Additional studies on B-site doping of Nb ions in BFO films showed change in the domain structures due to doping induced change in lattice anisotropy while maintaining the stripe domain morphology with 109° domain wall. Finally, this long-range array of ferroelectric and ferroelastic domains can be useful for optoelectronic devices and ferroelastic templates for strain coupled artificial magnetoelectric heterostructures.

  • Highly directional-dependent metal-insulator transition is observed in epitaxial double perovskite LaBaCo 2O 5.5+δ films. The film exhibit metallic along [100], but remain semiconducting along [010] under application of a magnetic field parallel to the surface of the film. The physical origin for the properties is identified as in-plane tensile strain arising from oxygen vacancies. First-principle calculations suggested the tensile strain drastically alters the band gap, and the vanishing gap opens up [100] conduction channels for Fermi-surface electrons. Lastly, our observation of strain-induced highly directional-dependent metal-insulator transition may open up new dimension for multifunctional devices.
  • As-grown superconducting YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital y}} thin films with various thicknesses were successfully grown on lattice-matched NdGaO{sub 3} substrates by ArF laser ablation deposition. An as-grown 2000-A-thick film has a zero-resistance temperature ({ital T}{sub {ital c}}) at 90 K and a 170-A-thick film has a {ital T}{sub {ital c}} at 88 K. The existence of a thin interfacial diffusion layer between a 170-A-thick film and the substrate was observed by Auger electron spectroscopy. Rutherford backscattering spectroscopy suggest that as-grown YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital y}} films on NdGaO{sub 3} substrates are high-quality crystals. It is demonstrated that the NdGaO{sub 3}more » has considerable potential as an electronic substrate material by less interfacial diffusion layer and good crystallinity of grown thin films.« less
  • We investigate the strain relaxation and surface morphology of epitaxial SrTiO{sub 3} (STO) films grown on (001){sub O} and (110){sub O} planes of orthorhombic NdGaO{sub 3} (NGO), and (001) plane of cubic (LaAlO{sub 3}){sub 0.3}(Sr{sub 2}AlTaO{sub 6}){sub 0.7} (LSAT) substrates. Although the average lattice mismatches are similar, strikingly regular crosshatched surface patterns can be found on STO/NGO(001){sub O}[(110){sub O}] films, contrary to the uniform surface of STO/LSAT(001). Based on the orientation and thickness dependent patterns and high-resolution x-ray diffractions, we ascribe the crosshatch morphology to the anisotropic strain relaxation with possibly the 60° misfit dislocation formation and lateral surface stepmore » flow in STO/NGO films, while an isotropic strain relaxation in STO/LSAT. Further, we show that the crosshatched STO/NGO(110){sub O} surface could be utilized as a template to modify the magnetotransport properties of epitaxial La{sub 0.6}Ca{sub 0.4}MnO{sub 3} films. This study highlights the crucial role of symmetry mismatch in determining the surface morphology of the perovskite oxide films, in addition to their epitaxial strain states, and offers a different route for designing and fabricating functional perovskite-oxide devices.« less
  • The microstructure of (1 1 0){sup pc}-oriented epitaxial SrRuO{sub 3} (SRO) thin films grown by pulsed laser deposition on (1 0 0)YSZ (YSZ: yttria-stabilized zirconia) single crystal substrates with a miscut angle of 5{sup o} has been investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The films grow epitaxially with their pseudocubic (1 1 0) plane parallel to the (1 0 0) surface of the YSZ single crystal substrate, and with an in-plane orientation relationship of [{ovr 1} 1 1]{sub SRO}//[0 1 1]{sub YSZ}. Cross-sectional TEM investigations show that the films have a rough, facetted surface. Generally, fourmore » different azimuthal domains are present in (1 1 0)SRO films on (1 0 0)YSZ. Their number can be significantly reduced using annealed offcut YSZ substrates before SRO deposition, and this reduction effect is shown to be much stronger on [0 1 1]-miscut (1 0 0)YSZ than on [0 0 1]-miscut ones. Size and morphology of the azimuthal pseudocubic domains and their domain boundaries, as well as of anti-phase domains and their domain boundaries are studied by plan-view and cross-section TEM.« less
  • A characteristic feature of epitaxial (110) thin films of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} and PrBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} on (110)SrTiO{sub 3} substrates is that the films have a tendency to crack along the (001) planes. We have studied the crack spacing as a function of deposition temperature and film thickness. The experimental data have been found to be in excellent agreement with a theoretical analysis of the crack spacings in brittle films. The study has allowed us to determine the critical thickness below which no cracks are expected to form as a function of temperature for (110) films ofmore » YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}, PrBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}, and YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}/ PrBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} bilayers.« less
