The ferroelectric behavior of barium strontium titanate (BST) in thin film form has been investigated in order to study the possibility of using BST for ferroelectric gate-field effect transistor (FeFET) for memory devices application. BST thin films have been fabricated as Al/BST/Pt/SiO2/Si-gate configuration. The variation of the dielectric constant (ε) and tan δ with frequency have been stud...

Due to the growing demand of energy and wastage energy, there exists an interest storing so that it could be utilized efficiently. Capacitors are materials designed for such application. Ferroelectric known their application as capacitors. Of materials, perovskites preferable classes have been used Barium strontium titanate nanomaterial is a member which encompasses smaller dielectric loss, ele...

Barium strontium titanate exhibits ferroelectric or paraelectric behavior that depends upon the composition and other factors, making it suitable for several applications. We have adopted conventional solid-state reaction route to synthesize magnesium-substituted barium with magnesium concentration (Mg = 0, 0.005, 0.010, 0.015). X-ray diffraction has confirmed perovskite cubic single phase. The...

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...

We describe the experimental measurement of phase-conjugate reflectivity versus various ratios of input-beam intensities in photorefractive barium titanate and strontium barium niobate crystals. The experimental results are compared with the theoretical prediction from the coupled-wave theory. Three different methods to measure the nonlinear coupling constant of the crystal are also presented a...

Here, we report a previously unreported low-temperature curable barium strontium titanate (BaXSr1−XTiO3) or BST dielectric nanoparticle ink which shows high tunability for printed electronics/additive manufacturing applications. The newly formulated is optimized to print in aerosol jet printers and can be cured at 150°C, will allow the fabrication of tunable radio-frequency (RF) microwave (MW) ...
