Films having a dielectric constant and loss comparable to single-crystal values have been achieved and the best value of the pyroelectric coefficient was found to be about four times smaller than that of single-crystal lithium tantalate.doi:10.1016/0167-577X(84)90009-0...
LN crystals exhibit pronounced anisotropy, with distinct atomic arrangements on different crystal planes. This results in significant variations in the properties of LN on different crystal facets, such as the piezoelectric coefficient (e), dielectric constant (ε), and others. These factors impact per...
Temperature dependences of dielectric properties of the lithium tantalate crystals have been studied in temperature range 25-800掳C and frequency range 10 Hz-10 MHz. The existence of dielectric nonlinearity in comparatively weak (in relation to coercive) fields was revealed. Dielectric nonlinearity in ...
optical constants (including refractive index, complex dielectric constant, absorption, reflection and transmission coefficients, emissivity)We present a Sellmeier equation that describes the refractive index dispersion of congruently grown LiTaO3, accurate from 0.3 to 5 m and from 23 to above 200掳C. ...

In particular, we have studied the relaxation of the Li+ ions, which manifests itself on both the dielectric constant and the elastic constant by a peak in the imaginary part and a step in the real part. In the less concentrated crystal, the dielectric results are analyzed in the form of...
Due to their high dielectric constant, LiNbO3 and LiTaO3 single crystals have been used as piezoelectric substrates in Surface Acoustic Wave (SAW) biosensors, for the detection of small molecules in liquid media. SAW based biosensors offer the possibility of observing real-time binding events of ...

Lithium niobate and lithium tantalate also have specialised applications in optics in the production of electronic grade crystals for use in electronic oscillators. Lithium has been found effective in assisting silicon nanowelds in electronic components for electric batteries and other devices. Glass ...
