Sputtered Modified Barium Titanate for Thin-Film Capacitor Applications
New apparatus and a new process for the sputter deposition of modified barium titanate thin-films were developed. Films were deposited at temperatures up to 900 °C from a Ba₀.96Ca0.04Ti0.82Zr0.18O₃ (BCZTO) target directly onto Si, Ni and Pt surfaces and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Film texture and cryst...
متن کاملSynthesis of Barium-zinc-titanate Ceramics
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered at 1250 °C for 2h with a heating rate of 10 °C/min. X-ray diffraction analysis of obtained powders and sintered samples was performed in order to investigate changes of the pha...
متن کاملRadiopaque Strontium Fluoroapatite Glass-Ceramics
The controlled precipitation of strontium fluoroapatite crystals was studied in four base glass compositions derived from the SiO2-Al2O3-Y2O3-SrO-Na2O-K2O/Rb2O/Cs2O-P2O5-F system. The crystal phase formation of these glasses and the main properties of the glass-ceramics, such as thermal and optical properties and radiopacity were compared with a fifth, a reference glass-ceramic. The reference g...
متن کاملThickness independence of true phase transition temperatures in barium strontium titanate films
The functional properties of two types of barium strontium titanate ~BST! thin film capacitor structures were studied: one set of structures was made using pulsed-laser deposition ~PLD! and the other using chemical solution deposition. While initial observations on PLD films looking at the behavior of Tm ~the temperature at which the maximum dielectric constant was observed! and Tc* ~from Curie...
متن کاملThermal Properties of SiOC Glasses and Glass Ceramics at Elevated Temperatures
In the present study, the effect of the chemical and phase composition on the thermal properties of silicon oxide carbides (SiOC) has been investigated. Dense monolithic SiOC materials with various carbon contents were prepared and characterized with respect to their thermal expansion, as well as thermal conductivity. SiOC glass has been shown to exhibit low thermal expansion (e.g., ca. 3.2 × 1...
