Dielectric and pyroelectric properties of barium strontium titanate films on orthorhombic substrates with „110... / / „100... epitaxy
The role of anisotropic misfit strains on the spontaneous polarization, dielectric properties, and pyroelectric response of 110 oriented Ba0.6Sr0.4TiO3 BST 60/40 thin films on 100 orthorhombic substrates is analyzed theoretically. The anisotropic in-plane strain state and the rotation of the elastic and the electrostrictive constants of the BST 60/40 films result in strongly directional and uni...
متن کاملSputtered 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 کاملThe 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 ...
متن کاملDc and Ac Electrical Properties of Ptc Barium Titanate Ceramics
The dc and ac electrical properties of PTC barium titanate ceramics were measured in the temperature range from 30 to 450°C. The Heywang's model alone is not sufficient to perform a quantitative analysis of the results. The heterogeneity of the system is taken into account.
متن کاملEffect of re-oxidation firing on PTCR properties of Sm-doped barium titanate ceramics
The effect of reduction and re-oxidation firing on the PTCR properties of Sm-doped barium titanate ceramics was investigated for the application in multilayered PTC thermistors. The lattice parameters a, and c decreases monotonically with increasing oxygen concentration in the re-oxidation atmosphere, which seems to be related with an electrostatic Coulomb interaction between an oxygen vacancy ...
