“…Electric-field cycling was carried out to track the evolution of the strain-electric-field and current-electric-field hysteresis behavior from the virgin state of the material (never exposed to an electric-field prior to measurement) 35 . The change in the switching behavior as a function of the number of prior electric-field cycles evidences the electric-field history dependence.…”

“…This provides valuable information pertaining to the evolution of polarization and, in particular, strain 35 . Here the current-electric-field (I-E) and strain-electric-field (S-E) hysteresis are displayed in favour of polarization-electric-field (P-E) hysteresis (Fig.…”

“…strain-electric field hysteresis loops were obtained at room temperature using a capacitance nanosensor device (NPL, Teddington, UK). 22,23 For piezoelectric constant measurements the samples were poled under DC conditions with an electric field of 10 kV/mm for 15 min in silicone oil at room temperature. The piezoelectric constant (d 33 ) was characterized using a piezo-d 33 meter (ZJ-3B, Institute of Acoustics, Academia Sinica).…”

The microscopic origin of the grain size effects on the dielectric, piezoelectric, and thermal depoling properties of Aurivillius phase Bi3.15Nd0.85Ti3O12 was investigated. Using atomic force microscopy, domain walls were observed in micrometer grain size ceramics, but gradually disappeared with reducing grain size and were not found in ceramics with 90 nm grain size. In strain-electric field butterfly loops, the strain decreased with decreasing grain size indicating a decreasing contribution of non-180° domain walls switching to the strain. Lattice distortion (a−b)/b decreased with decreasing grain size. The thermal depoling resistance decreased with decreasing grain size, due to increasing internal mechanical stresses.

“…The anomalies described above as well as other phenomena in heterogeneous materials are now explained by the increased role of the near-surface interactions in such systems, among which the increase of defects concentration near the boundaries of different areas in heterogeneous materials are traditionally considered, [19][20][21][22][23][24][25][26][27][28][29][30] but a more in-depth consideration of these phenomena is still absent.…”

Negative thermal expansion properties in tetragonal NbPO 5 from the first principles studies AIP Advances 7, 035202 (2017); https://doi.org/10.1063/1.4977874In silico modeling and investigation of self-heating effects in composite nano cantilever biosensors with integrated piezoresistors AIP Advances 7, 035108 (2017) Dielectric properties of polycrystalline ferroelectric ceramics and ferroelectrics with compensated impurities were investigated. Electric fields at the boundaries between crystallites and the fields created by a random distribution of impurities were calculated. It was shown, that the influence of these fields leads to an increase in the effective dielectric constant and to a displacement of the phase transition temperature in these ferroelectrics to lower temperatures. These effects are associated with an asymmetric nonlinear dependence of the thermodynamic potential near to the equilibrium value of spontaneous polarization vector. The asymmetry of this dependence in the random electric and elastic fields with a zero mean value reduces the length of the spontaneous polarization vector. The polarization reduced by the indicated fields lies in a region with less curvature of the thermodynamic potential that effectively means growth the value of dielectric constant of the studied system. © 2017 Author(s).
