Ferroelectric interaction and polarization studies in BaTiO{sub 3}/SrTiO{sub 3} superlattice

Journal Article Sarkar, Asis ; Krupanidhi, S B - Journal of Applied Physics

Ferroelectric superlattice structures consisting of alternating layers of BaTiO{sub 3} and SrTiO{sub 3} with variable interlayer thickness were grown on Pt (111)/TiO{sub 2}/SiO{sub 2}/Si (100) substrates by pulsed laser deposition. The presence of superlattice reflections in the x-ray diffraction pattern clearly showed the superlattice behavior of the fabricated structures over a range of 6.4-20 nm individual layer thicknesses. Depth profile conducted by secondary ion mass spectrometry analysis showed a periodic concentration of Ba and Sr throughout the film. Polarization hysteresis and the capacitance-voltage characteristics of these films show clear size dependent ferroelectric characteristics. The spontaneous (P{sub s}) and remnant (P{submore »« less

Soft-mode spectroscoopy of epitaxial BaTiO{sub 3}/SrTiO{sub 3} superlattices.

It is demonstrated that soft modes in 240 nm think BaTiO{sub 3}/SrTiO{sub 3} ferroelectric superlattices can be probed by infrared reflectivity measurements, which allows us to estimate the intrinsic in-plane dielectric constants of such thin superlattice slabs. The infrared reflectance spectrum of the (BaTiO{sub 3}){sub 8}/(SrTiO{sub 3}){sub 4} superlattice epitaxially grown a DyScO{sub 3} single-crystal substrate reveals a strong polar mode with a transverse optic frequency of about 70 cm{sup -1} and moderate damping (about 30 cm{sup -1}). Our analysis of the experimental results is combined with the first-principles based theoretical evaluation of optical polar modes in a model systemmore »« less

Epitaxial growth of (111)-oriented BaTiO{sub 3}/SrTiO{sub 3} perovskite superlattices on Pt(111)/Ti/Al{sub 2}O{sub 3}(0001) substrates

Journal Article Panomsuwan, Gasidit ; Takai, Osamu ; Saito, Nagahiro ; ... - Applied Physics Letters

Symmetric BaTiO{sub 3}/SrTiO{sub 3} (BTO/STO) superlattices (SLs) were epitaxially grown on Pt(111)/Ti/Al{sub 2}O{sub 3}(0001) substrates with various modulation periods (Λ = 4.8 − 48 nm) using double ion beam sputter deposition. The BTO/STO SLs exhibit high (111) orientation with two in-plane orientation variants related by a 180° rotation along the [111]{sub Pt} axis. The BTO layer is under an in-plane compressive state, whereas the STO layer is under an in-plane tensile state due to the effect of lattice mismatch. A remarkable enhancement of dielectric constant is observed for the SL with relatively small modulation period, which is attributed to bothmore »« less

Influence of interfacial coherency on ferroelectric switching of superlattice BaTiO₃/SrTiO₃

Journal Article Wu, Pingping ; Ma, Xingqiao ; Li, Yulan ; ... - Applied Physics Letters

Switching behavior of (BaTiO₃)₈/(SrTiO₃)₄ heterostructure superlattice grown on SrTiO₃ substrate was studied by employing the phase field method. To investigate the constraint effect of the substrate on switching, three types of superlattice/substrate interface mechanical relaxation conditions were considered, i.e. the fully ommensurate, partially relaxed and fully relaxed. Our simulation results demonstrated that the hysteresis loops under the three types of constraints were very different. The interfacial coherency affects dramatically the coercivity and remanence of the superlattice films. The mechanism of the hysteresis loop varying with interfacial coherency was analyzed by the ferroelectric domain configuration and its evolution during the switchingmore »« less

Emergent chirality in the electric polarization texture of titanate superlattices

Journal Article Shafer, Padraic ; García-Fernández, Pablo ; Aguado-Puente, Pablo ; ... - Proceedings of the National Academy of Sciences of the United States of America

Chirality is a geometrical property by which an object is not super-imposable onto its mirror image, thereby imparting a handedness. Chirality determines many important properties in nature—from the strength of the weak interactions according to the electroweak theory in particle physics to the binding of enzymes with naturally occurring amino acids or sugars, reactions that are fundamental for life. In condensed matter physics, the prediction of topologically protected magnetic skyrmions and related spin textures in chiral magnets has stimulated significant research. If the magnetic dipoles were replaced by their electrical counterparts, then electrically controllable chiral devices could be designed. Complexmore »« less
