Electrooptic and piezoelectric measurements in photorefractive barium titanate and strontium barium niobate
We have measured the low-frequency ("unclamped") electrooptic and piezoelectric coefficients in undoped BaTiO, and SrSa, -Nh2O6 (x = 0.61) crystals using interferometric techniques. The Contribution of the piezoelectric effect to the Pockels measurements is discussed. For an applied ac electric field in the range 0.1-200 V/cm, the electrooptic and piezoelectric effects are linear in the magnitu...
متن کاملAn Investigation of PLD-Deposited Barium Strontium Titanate (BaxSr1-xTiO3) Thin Film Optical Properties
Reflectance and transmittance parameters of pulsed laser deposited barium strontium titanate (BST) were investigated using spectrophotometric methods. Three stoichiometries consisting of BaxSr1−xTiO3 (x = 0.30, 0.40, 0.50) were deposited on glass substrates using oxygen partial pressures of 1.3 Pa ± 0.13 Pa at 500 ̊C. Subsequently, the measured optical parameters were employed to determine the r...
متن کاملstudies on nano barium strontium titanate/cellulose derivatives composites
studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...
متن کاملRadio Frequency Applications of Barium Strontium Titanate Thin Film Tunable Capacitors
TOMBAK, Ali. Radio Frequency Applications of Barium Strontium Titanate Thin Film Tunable Capacitors. (Under the supervision of Amir S. Mortazawi). Properties of thin film barium strontium titanate (BST) based capacitors for RF and microwave components were studied. The capacitors were measured for their tunability, loss tangent, frequency dependence of dielectric permittivity, and behavior at l...
متن کاملBarium titanate as a ferroelectric and piezoelectric ceramics
Barium titanate is a member of a large family of compounds with the general formula ABO3 called perovskites, as the crystal size of barium titanate increases and at critical crystalline size crystal structure of barium titanate transformed from cubic to tetragonal. Transformation of crystal structure is also take place at Curi temperature. Cubic structure show paramagenatic behavior while tetra...
