Three-dimensional dispersion induced by extreme tensile strain in La_(2−x)Sr_xCuO_4 films

Davor Pavuna, Slobodan Mitrovic, Dominique Cloëtta, Claudia Cancellieri, Mike Abrecht

The electronic band structure probed by angle-resolved photoemission spectroscopy on thin epitaxial La_(2−x)Sr_(x)CuO_(4) films under extreme tensile strain shows anomalous features compatible with c-axis dispersion. This result is in striking contrast wit ...

Influence of Ta and Ti Doping on the High Field Performance of (Nb,Ta,Ti)(3)Sn Multifilamentary Wires based on Osprey Bronze with High Tin Content

Davide Uglietti

Ta and Ti are the most widely used additions for technical Nb3Sn multifilamentary superconductors. These elements are known to influence grain growth, grain morphology and chemical composition in the A15 layer, hence the current carrying properties of the ...

Piezoelectric anisotropy: Enhanced piezoelectric response along nonpolar directions in perovskite crystals

Nava Setter, Dragan Damjanovic, Matthew Davis, Marko Budimir

This paper discusses the mechanisms that can contribute to the enhanced longitudinal piezoelectric effect along nonpolar directions in perovskite crystals, such as BaTiO3, PbTiO3, KNbO3, Pb(Mg1/3Nb2/3)O-3-PbTiO3 and Pb(Zn1/2Nb2/3)O-3-PbTiO3. Piezoelectric ...

Ionic polarizability of conductive metal oxides and critical thickness for ferroelectricity in BaTiO3

Nava Setter, Alexander Tagantsev, Guido Gerra

We report a first-principles investigation of ultrathin BaTiO3 films with SrRuO3 electrodes. We find that the ionic relaxations in the metal-oxide electrode play a crucial role in stabilizing the ferroelectric phase. Comparison with frozen-phonon calculati ...

Characterization of perovskite powders for cathode and oxygen membranes made by different synthesis routes

Jan Van Herle, Philippe Buffat, Sébastien Vaucher, Elena Suvorova Buffat, Nicolas Xanthopoulos

Strontium lanthanum manganite (LSM) and lanthanum ferrite (LSF) perovskite cathode and oxygen membrane materials were synthesized using different techniques: spray pyrolysis, a modified citrate route, oxalate and carbonate co-precipitations. The use of Ca, ...

Correlation between dielectric anisotropy and positive or zero transverse piezoelectric coefficients in perovskite ferroelectric single crystals

Nava Setter, Dragan Damjanovic, Matthew Davis

The transverse piezoelectric coefficient (d(31)(star)) has been calculated for tetragonal barium titanate (BT) and lead titanate (PT) cut along nonpolar axes, over a range of temperatures, using the phenomenological Landau-Ginzburg-Devonshire theory. It is ...

Domain engineering of the transverse piezoelectric coefficient in perovskite ferroelectrics

Nava Setter, Dragan Damjanovic, Matthew Davis

The transverse piezoelectric coefficient d(31)*, has been calculated for the six domain-engineered structures occurring in perovskite single crystals, using data for rhombohedral PMN-33PT [0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3)], orthorhombic potassium niobate ...

Strain relaxation of epitaxial SrTiO3 thin films on LaAlO3 by two-step growth technique

Nava Setter, Paul Muralt, Alexander Tagantsev, Konstantin Astafiev

Using pulsed-laser deposition, a two-step growth technique was applied to epitaxial SrTiO3 (STO) thin films on LaAlO3 substrates providing a way to obtain an effective strain relaxation in these films otherwise strained due to lattice mismatch between film ...
