Abstract

The lattice structure of (110)-oriented BiFeO{sub 3} epitaxial thin layers has been identified by synchrotron x-ray diffraction. By using (221) and (22{bar 1}) peaks in the (HHL) zone, a ground state monoclinic M{sub b} phase has been observed with lattice parameters of ({beta}; a{sub m}/{radical}2 and c{sub m})=(89.35{sup o}; 3.985 and 3.888 {angstrom}). These results demonstrate a change in phase stability from rhombohedral in bulk single crystals, to monoclinic in epitaxial thin films with two domain states whose polarization is slightly tilted away from [110] towards [111].

Synthesis and ferroelectric properties of epitaxial BiFeO{sub 3} thin films grown by sputtering

Journal Article Das, R; Kim, D; Baek, S; ... - Applied Physics Letters

We have grown epitaxial BiFeO{sub 3} thin films with smooth surfaces on (001) (101), and (111) SrTiO{sub 3} substrates using sputtering. Four-circle x-ray diffraction and cross-sectional transmission electron microscopy show that the BiFeO{sub 3} thin films have rhombohedral symmetry although small monoclinic distortions have not been ruled out. Stripe ferroelectric domains oriented perpendicular to the substrate miscut direction and free of impurity phase are observed in BiFeO{sub 3} on high miscut (4 deg.) (001) SrTiO{sub 3}, which attributes to a relatively high value of remanent polarization ({approx}71 {mu}C/cm{sup 2}). Films grown on low miscut (0.8 deg.) SrTiO{sub 3} have amore »« less

Exploring Polarization Rotation Phase Instabilities in Super-Tetragonal BiFeO3 Epitaxial Thin Films and Their Technological Implications

Journal Article Cao, Ye; Yang, Mr.; Jesse, Stephen; ... - Advanced Electronic Materials

Many functional properties of ferroelectrics are underlain by structural instabilities, which render these materials very susceptible to small alternating applied fields (electric, mechanical, etc.) through certain constitutive coupling relations, e.g., elastic compliance and piezoelectric response, and often such instabilities can be shifted by static applied fields thus meaning tunable dynamic properties. Structural instabilities are naturally accommodated on the brink of morphotropic phase boundaries (MPB s) where multiple phases of small energy difference coexist in different crystallographic forms. Canonical MPB is realized through compositional mixture, as is typically exemplified by Pb(Zr1-xTix)O3 solid solutions and relaxor ferroelectrics of (1-x)PbMg1/3Nb2/3O3-xPbTiO3.

Growth rate induced monoclinic to tetragonal phase transition in epitaxial BiFeO{sub 3} (001) thin films

Journal Article Huajun, Liu; Ping, Yang; Kui, Yao; ... - Applied Physics Letters

Epitaxial BiFeO{sub 3} thin films were deposited on SrRuO{sub 3} buffered SrTiO{sub 3} (001) substrates at different growth rates by varying the radio frequency sputtering power. With increasing growth rate, the crystal structure of BiFeO{sub 3} films develops from monoclinic lattice to a mixture phase of tetragonal lattice T{sub 1} with c/a{approx}1.05 and giant tetragonal lattice T{sub 2} with c/a{approx}1.23, finally to a single tetragonal phase T{sub 2}, as shown by high resolution synchrotron x-ray diffraction reciprocal space mappings. The observed phase transitions, induced by film growth rate, offer an alternative strategy to manipulate crystalline phases in epitaxial ferroelectric thinmore » films.« less

Ferroelectric Self-Poling, Switching, and Monoclinic Domain Configuration in BiFeO ₃ Thin Films

Journal Article Beekman, C.; Siemons, W.; Chi, M.; ... - Advanced Functional Materials

Self-poling of ferroelectric films, i.e., a preferred, uniform direction of the ferroelectric polarization in as-grown samples is often observed yet poorly understood despite its importance for device applications. The multiferroic perovskite BiFeO₃, which crystallizes in two distinct structural polymorphs depending on applied epitaxial strain, is well known to exhibit self-poling. This study investigates the effect of self-poling on the monoclinic domain configuration and the switching properties of the two polymorphs of BiFeO₃ (R' and T') in thin films grown on LaAlO₃ substrates with slightly different La_0.3Sr_0.7MnO₃ buffer layers. This study shows that the polarization state formed during the growth actsmore »« less
