Effect of Sr-substitution on structure, dielectric relaxation and conduction phenomenon of BaTiO3 perovskite material

Optimization of switching charge and recoverable energy density mediated by structural transformation in Sr-substituted BaNiO3 perovskites

“…here q denotes the Bragg's angle, b is the peak broadening or full-width at half-maxima (FWHM), k represents Scherrer's constant (shape factor), and l is the wavelength of the X-rays (1.5406 Å for CuK a ). 42 It was observed that with the increase in substitution contents, the crystallite size increased, but the porosity rst decreased for the BSN-1 sample and then gradually increased from 22.3% to 28.9%, however, it remained less than that of the pure BN sample (34.7%) as shown in Fig. 3(c).…”

Study of the effect of the substitution of Fe by Ti on the microstructure and the physical properties of the perovskite system La0.67Ca0.2Ba0.13Fe1−xTixO3 with x = 0 and 0.03 at low temperatures

“…On the other side in the variable distance hopping transport model the conductivity is expressed by the following Mott relation: 46 with T 0 is called the Mott temperature and is determined from the slope of the linear fit in the low-temperature region as shown in Fig. 3e .…”

Epitaxial growth of (Ba0.7Sr0.3)TiO3 thin films on GdScO3 substrates by magnetron sputtering

“…In this work, we investigated the epitaxial growth of ferroelectric Ba 0.7 Sr 0.3 TiO 3 on GdScO 3 (110) substrates with the ScO 2 surface using sputtering deposition. Ferroelectric Ba 0.7 Sr 0.3 TiO 3 (BST70) near room temperature has a tetragonal structure with a = 3.9773 Å and c = 3.9709 Å, 13 which is quite different from the orthorhombic GdScO 3 (GSO) with a = 5.4862 Å, b = 5.7499 Å and c = 7.9345 Å. 14 However, by aligning [100]/[010] directions of the BST70 with [110]/[001] directions of the GSO, the in-plane lattice mismatches between the BST70 film and the GSO substrate are ∼0.0906% and 0.0907%, respectively.…”
