An approach for correlating the structural and electrical properties of Zr⁴⁺-modified SrBi₄Ti₄O₁₅/SBT ceramic

Abstract

In the present work, zirconium (Zr) modified strontium bismuth titanate (SBT) ceramics were prepared by soild state reaction route and its effects on the structural and electrical properties were thoroughly investigated.

Frequency and temperature-dependence of dielectric permittivity and electric modulus studies of the solid solution Ca0.85Er0.1Ti1−xCo4x/3O3 (0 ≤ x ≤ 0.1)

“…In fact, the dielectric constant of the materials is linearly proportional to the average value of grain size. 43 Therefore, the decrease of dielectric constant and loss tangent as a function of Co doping is due to the decrease of grain size, which is in agreement with the previous results (conduction mechanism). 33 This indicates that there is a strong relation between the conduction process and the dielectric polarization in these Co doped Ti.…”

Structural and multiferroic properties in double-layer Aurivillius phase Pb0.4Bi2.1La0.5Nb1.7Mn0.3O9 prepared by molten salt method

“…The dielectric loss increases slightly with temperature below 600 K, and then more rapidly at higher temperature, which can also indicate a transition to the paraelectric phase where the sample becomes more conducting. Moreover, at high temperature, the electrical conductivity is enhanced by thermal effects as is the case for most semiconductors, resulting in a significant increase of the dielectric loss [23].…”

Dielectric and electrical properties of annealed ZnS thin films. The appearance of the OLPT conduction mechanism in chalcogenides

“…32 Indeed, the evolution of 3 00 is impacted by several factors 33 like the lattice vibration mode, the oxygen vacancies, the presence of secondary phases 34 and the grain size. 35 Thus, the increment dielectric loss with temperature is a result of the impact of temperature on these intrinsic and extrinsic factors which were temperature dependent. The increase of dielectric loss with annealing temperature is due to the increase of grain size as investigated by structural analysis and to the substitution of the sulfur by oxygen in the lattice which induced by thermal annealing.…”
