“…The model was previously tested in this version for the calculation of bulk properties of single-domain tetragonal BaTiO 3 like the ferroelectricity and optical anisotropy, as well as the linear electro-optical coefficients [36,37]. Furthermore the same model was successfully applied for modelling electric and optical properties of LiNbO 3 single crystals [38], and also within 180 • ferroelectric domain walls in BaTiO 3 [39]. Based on those experiences which agree excellently well with the corresponding experimental data, we initiate here the application of this model to the more complicated 90 • ferroelectric domain wall in BaTiO 3 at room temperature.…”

The electric and optical properties within 90 • ferroelectric domain walls of tetragonal barium titanate (BaTiO 3) are theoretically examined at room temperature using a microscopic model which is based on the orbital approximation in correlation with the dipole-dipole interaction. We find that when perpendicularly crossing the domain wall,the variation of the spontaneous polarization and refractive indices does not depend on the thickness of the domain wall which varies between 1.5 and 2.5 nm. Moreover, within the domain wall, the refractive indices n 2 and n 3 , corresponding to light polarized parallel to the principal axes y p and z p , respectively, exhibit an important transition in which n 2 transforms from the ordinary to the extraordinary state, while n 3 behaves oppositely to n 2 .

“…5,[12][13][14][15] In recent years, LNO has been intensively investigated as an important ferroelectric material owing to its high spontaneous polarization of 0.70 C m −2 and high Curie temperature of 1210 °C. [16][17][18] The DWC property has been intensively studied in single-crystal LNO films for the preparation of memristors. 8,10,19) An on/off ratio as high as 10 12 has been reached by the single-crystal LNO memristor.…”

LiNbO3 (LNO) is currently intensively studied as an important ferroelectric material. In this work, polycrystalline LNO films were prepared through a sputtering technique, and their ferroelectricity-related resistive switching property was investigated using a device structure of PtSi/SiO2/LNO/Pt. The device exhibits a volatile resistance switching property at lower positive sweeping voltages and a stable bipolar nonvolatile switching property at higher sweeping voltages. The resistive switching mechanism of the device is discussed based on the domain wall conductivity characteristics of the polycrystalline LNO thin films. The PtSi/SiO2/LNO/Pt memristor device has potential applications in memory and artificial neural synapses.

“…LiNbO 3 finds its application also in the field of holographic imaging, optical waveguides and modern optical parametric oscillators [8][9][10] . Its large spontaneous polarization and non linear optical activity make it favorite in the thermal, electrical and optical areas 11,12 . Its superior piezoelectric performance makes it a potential candidate for replacing quartz.…”

Abstract:The second and third-order elastic constants and pressure derivatives of second-order elastic constants of trigonal LiNbO 3 (lithium niobate) have been obtained using the deformation theory. The strain energy density estimated using finite strain elasticity is compared with the strain dependent lattice energy density obtained from the elastic continuum model approximation. The second-order elastic constants and the non-vanishing third-order elastic constants along with the pressure derivatives of trigonal LiNbO 3 are obtained in the present work. The second and third-order elastic constants are compared with available experimental values. The second-order elastic constant 11 C which corresponds to the elastic stiffness along the basal plane of the crystal is less than 33 C which corresponds to the elastic stiffness tensor component along the c-axis of the crystal. The pressure derivatives, dp C d ij / ′ obtained in the present work, indicate that trigonal LiNbO 3 is compressible. The higher order elastic constants are used to find the generalized Gruneisen parameters of the elastic waves propagating in different directions in LiNbO 3 . The Brugger gammas are evaluated and the low temperature limit of the Gruneisen gamma is obtained. The results are compared with available reported values.
