Effect of Different Weight Fraction on Dielectric Properties of Barium Ferrite-Barium Titanate Composites

The effect of stress on the dielectric properties of barium strontium titanate thin films

Barium strontium titanate thin films are being developed as capacitors in dynamic random access memories. These films, grown on silicon substrates, are under tensile residual stress. By a converse electrostrictive effect, the in-plane tensile stress reduces the capacitance in the thickness direction of the film. We measured the substrate curvature change upon the removal of the film, and found ...

H all effect and dielectric properties of Mn - doped barium titanate

BaMn Ti O (0# x # 0.01) ceramics have been prepared using a sol–gel method. The Hall coefficient, x 12x 3 leakage conductance and dielectric constant were measured. The Hall effect confirms that the charge carriers of the ceramics are electrons, and the electronic concentration n 5 1/ ueRu decreases with increasing Mn 31 41 concentration. We propose that Mn and Mn substitution of Ti can partial...

Physical structure of P(VDF-TrFE)/barium titanate submicron composites

Hydrogen-related dynamic dielectric behavior of barium titanate single crystals

Barium titanate single crystals had been placed in 0.01M NaOH solution to deposit hydrogen on their electrodes through the electrolysis of water. Two kinds of time-dependent changes in dielectric properties of the single crystals were observed: One occurred in the course of hydrogen deposition and the other lasted for a long period of time after the deposition. The diffusion of hydrogen and in ...

studies 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...
