Effect of pH on electrical and optical properties of sol–gel derived microcrystalline Ba0.5Sr0.5TiO3 thin films

Influence of the Morphology of Barium Strontium Titanate Thin Films on the Ferroelectric and Dielectric Properties

“…BST0.3M and BST0.1M present similar characteristics, however, BST0.1M shows a better saturated loop and its properties are similar than that reported elsewhere [6]. The visible shift of the P -E curve to negative electric fields signifies that positive charges might be present at the bottom electrode-film interface due to a doubly charged oxygen vacancies at this region [16]. The shift of the hysteresis loop is more important in the case of BST0.1M which is composed of more individual layers and consequently was exposed to more annealing heat treatments.…”

Effect of 2-methoxyethanol on structure and dielectrical properties of (Pb0.25Ba0.15Sr0.6)Tio3 thin films by modified sol–gel technique

“…There are few reports about the effect of these parameters of sol on the properties of film for systems like BST thin films. Somnath et al [14] have shown the effect of pH of the precursor sol on the grain morphology, electrical and optical properties of sol-gel-derived-Ba 0.5 Sr 0.5 TiO 3 thin films. Yongping Ding et al [15] investigated the effects and mechanism of chemical additives (acetylacetone) on the pyrolysis evolution and microstructure of sol-gel-derived BST thin films.…”

Influence of the Grain Size on the Conduction Mechanism of Barium Strontium Titanate Thin Films

“…Furthermore, the AFM results show that Sample A has the smallest grains; therefore, it has the highest resistance. Hence, as the grain size decreases the area of the grain boundaries and electrode interfaces increase [13,14], and this leads to an increase in the grain boundaries-electrode resistance due to the increase of the space charge density.…”
