In this article, we have studied passive voltage amplification in FE-FE-DE heterostructure. We have stacked two different ferroelectric oxides; one is second-order transition ferroelectric material (continuous transition ferroelectric material) and the other is first-order transition ferroelectric material (discontinuous transition ferroelectric material). Both ferroelectric materials have different polarities of anisotropy constant (𝜷), which is tuned by varying the ferroelectric thickness and thus leads to its cancellation. The nullification of the anisotropy constant will reduce the nonlinearity of the ferroelectric oxide and provide efficient matching between the ferroelectric and dielectric capacitance, which in turn delivers the higher voltage amplification in the heterostructure. Also, dynamic response and temperature analysis of heterostructure are studied further. It is observed that dielectric when added in series with the isolated ferroelectric capacitor the curie temperature shifts to a lower value.

“…It possesses crystalline properties similar to general perovskites with a cubic nature and with the chemical formula Ba 1-x Sr x TiO 3 [10]. The ferroelectric materials mentioned above, the solid solution composition of ferroelectric barium titanate (BaTiO 3 ) and paraelectric SrTiO3, BaSrTiO3 (BST) possess the best dielectric constant and have a relatively low loss over a wide range of frequencies, besides a low leakage current and large electric field tenability [11] [12].…”

The sol-gel process was utilized in the production of the ferroelectric material Ba0.7Sr0.3TiO3. Barium and strontium acetate were employed as sources for Ba and Sr, respectively, and Ti(IV) isopropoxide was used as a source for Ti. The acetic acid was utilized as a solvent for Ba and Sr acetate, whereas 2-methoxy ethanol was used as a stabilizer for Ti (IV) isopropoxide. The effect of high temperatures on electrical and structural were studied. The FESEM revealed the particle size of all samples with different temperatures. The XRD shows the Ba0.7Sr0.3TiO3 samples have a tetragonal phase for all temperatures (1000, 1100, 1200˚C). The high temperatures impacted tetragonality and the lattice constant (a, c); the lattice constant decreased at higher temperatures. The ferroelectric sample sintered at 1000 degrees Celsius had dielectric characteristics that were inferior to those of the Ba0.7Sr0.3TiO3sample sintered at 1100 and 1200ºC degrees Celsius. When the dielectric constant was graphed as a function of temperature, the Curie temperature appeared to be between (28-32) degrees Celsius.

Differential scanning calorimetry experiments have been performed for PbZr 1-x Sn x O 3 single crystals where 0 ≤ x ≤ 0.4 at the temperature range of 100 -600 K. The temperatures and orders of particular phase transitions have been determined and the phase diagram was compared to dielectric measurements. The first order character of the phase transitions in PbZr 1-x Sn x O 3 was discussed. The total transitions energy and entropy at the phase transitions were calculated. The excess specific heat and excess entropy associated with the phase transitions were analysed using Landau theory. The comparison of calorimetric data with the evolution of the order parameter indicates that the phase transitions in PbZr 1-x Sn x O 3 single crystals seem to follow a mean field Landau potential. The results are compared to the earlier dielectric and birefringence experiments.
