Dielectric dispersion and tunability of sol-gel derived Ba_xSr_1-xTiO₃thin films

Nonlinear dielectric properties of Ba1−xSrxTiO3 ceramics

“…[1]. Their functional properties have been intensively studied in relationship with their preparation technique and processing parameters, composition and microstructural properties, in single-crystal form, ceramics, epitaxial, polycrystalline films or heterostructures [1][2][3][4][5][6][7][8][9]. High tunability and dielectric constant and low losses are needed for the employment of BST in such applications.…”

Co-doped BST thin films for tunable microwave applications

“…However, BST materials with high dielectric constant and high tunability are usually associated with large dielectric loss [6]. According to Wang and Cheng [8], thin films crystallized by a high temperature annealing process would lead to the formation of n-type BST thin films with defects such as oxygen vacancies.…”

Tunable Barium Strontium Titanate Thin Films by CSD

“…In addition, these thin film capacitors are also expected to apply non-volatile memories with high velocity, large capacity and low power consumption [3]. BST solid solution has been expected as an important material for tunable microwave devices because of its Curie temperature depends upon the Ba/Sr ratio and composition, which are exhibit high dielectric constant at room temperature and relatively low dielectric loss, large electric field tunabilities [4,5]. Much effort have been paid to deposit good ferroelectric and dielectric thin films by various deposition methods for the BST thin films such as metal-organic chemical vapor deposition (MOCVD) [6] and CSD [7].…”
