Title: Fabrication and material properties of submicrometer SrTiO{sub 3} films exfoliated using crystal ion slicing

Abstract

The crystal quality of submicrometer-thick SrTiO{sub 3} films that are formed by exfoliation from bulk crystals using deep implantation with H-ion beams is investigated. Nuclear reaction analysis and Rutherford backscattering/channeling are used to measure the implantation depth, crystal-lattice disruption, and surface damage prior to exfoliation. The surface profiles of the exfoliated films are examined with atomic force microscopy; the roughness is shown to be reducible to subnanometer levels with postexfoliation mechanical polishing.

  • The pulsed laser deposition process of 300 nm thick films of Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}){sub 0.67}-(PbTiO{sub 3}){sub 0.33} on (001)-oriented SrTiO{sub 3} was studied by varying deposition pressure, substrate deposition temperature, laser fluence on the target and target-substrate distance. Perovskite phase pure, (001)-oriented, epitaxial smooth films were obtained in a narrow range of deposition parameters. The ferroelectric and dielectric properties of films fabricated within this parameter range still vary significantly. This shows the sensitivity of the system for growth conditions. The best film has a polarization value close to that expected for a (001) poled, stress free single crystal film.more » All films show deposition conditions dependent variations in the self-bias field. The self-bias is very stable during long cycling for films made at optimum deposition conditions. The piezoelectric coefficients of the films are strongly reduced with respect to bulk single crystal values due to the film clamping. The properties variations are ascribed to changes in the grain boundary properties in which film defects are expected to accumulate. Notably slight off-stoichiometry may cause localized screening charges, affecting specifically the polarization and dielectric constant.« less
  • We investigated infrared-active phonons of CaTiO3, SrTiO3, BaTiO3, and Ba0.5Sr0.5TiO3 thin films, and a (BaTiO3)5/(SrTiO3)5 artificial superlattice by a Fourier transform infrared spectrometer with a grazing angle (48{sup o}) incident reflectance method. The longitudinal phonon energies of the thin films were different from those of the bulk material due to the lattice strain of the substrate. The Ba0.5Sr0.5TiO3 thin film and (BaTiO3)5/(SrTiO3)5 superlattice showed different phonon modes due to structural discrepancies, even though their chemical compositions are similar. The Ba0.5Sr0.5TiO3 thin film showed a single phonon energy lying between the phonon energies of BaTiO3 and SrTiO3 thin films, while themore » (BaTiO3)5/(SrTiO3)5 superlattice well preserved the characteristic phonon modes of BaTiO3 and SrTiO3 thin films.« less
  • A process combining hydrofluoric acid (HF) and Ar{sup +} ion milling has been used to make YBa{sub 2}Cu{sub 3}O{sub {ital x}}/SrTiO{sub 3}/YBa{sub 2}Cu{sub 3}O{sub {ital x}}(YBCO/STO/YBCO) multilayer test circuits. Low-angle steps can be readily etched in STO and YBCO films with this process. YBCO lines crossing 5{degree} steps have about the same critical temperature {ital T}{sub {ital c}} (89{endash}90 K) and critical current density {ital J}{sub {ital c}} ({approx_gt}1{times}10{sup 6} A/cm{sup 2} at 86 K) as lines on planar surfaces. Via connections have the same {ital T}{sub {ital c}} as other circuit components and adequate critical currents for most circuitmore » designs. {copyright} {ital 1996 American Institute of Physics.}« less
  • Spinel -Al2O3 and NiAl2O4 thin films were grown on (001) SrTiO3 substrates by pulsed laser deposition. The high quality of epitaxial growth and cube-on-cube orientation of the films were confirmed by x-ray diffraction and transmission electron microscopy. The growth of NiAl2O4 thin films is related to the reaction between sequentially deposited -Al2O3 and NiO layers. These films were grown using a unique multi-target approach.
  • In this study, we have investigated the interfacial structure of epitaxial (Ba,Sr)TiO 3 films grown on (111)-oriented SrTiO 3 single-crystal substrates using transmission electron microscopy (TEM) techniques. Compared with the (100) epitaxial perovskite films, we observe dominant dislocation half-loop with Burgers vectors of a<110> comprised of a misfit dislocation along <112>, and threading dislocations along <110> or <100>. The misfit dislocation with Burgers vector of a <110> can dissociate into two ½ a <110> partial dislocations and one stacking fault. We found the dislocation reactions occur not only between misfit dislocations, but also between threading dislocations. Via three-dimensional electron tomography,more » we retrieved the configurations of the threading dislocation reactions. The reactions between threading dislocations lead to a more efficient strain relaxation than do the misfit dislocations alone in the near-interface region of the (111)-oriented (Ba 0.7Sr 0.3)TiO 3 films.« less
