Ac conductivity and relaxation mechanism in Ba0.9Sr0.1TiO3

“…), which makes it special for electronic applications such as multilayer and voltage tunable capacitors, infrared sensors, electro-optic devices, memories, etc. [5,6]. As it is well known, the tunability of a particular material shows how much the dielectric constant and other related proportion of the material can be changed upon an applied electric field and/or other experimental conditions.…”

Structural and dielectric properties of Ba0.5Sr0.5(SnxTi1−x)O3 ceramics obtained by the soft chemical method

“…The increase of sintering temperature also can be explained by the high covalent character of Sn, followed by evaporation and condensation mechanisms [60][61][62]. Table 2 [39,42,[63][64][65][66][67].…”

Complex impedance, dielectric relaxation and electrical conductivity studies of Ba1-xSrxTiO3ceramics

“…A well known solid solution of both BaTiO 3 and SrTiO 3 is barium strontium titanate (Ba 1−x S r x TiO 3 or BSxT), has been considered to be an important material for tunable microwave devices such as phase shifters, tunable filters, delay lines, tunable oscillators, induced piezoelectric transducer etc. This because of its high dielectric constant, large electric field tunabilities, relatively low dielectric loss, variable Curie temperature (from 243 to 127 °C) depending on the composition of strontium, large polarizations, large permittivity and large induced strains that are achievable [10][11][12][13]. On the other hand, it is known that all the above mentioned properties are basically influenced by the temperature and the frequency in perovskite structure-type materials.…”
