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 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 کاملInfluence of stoichiometry on the dielectric properties of sputtered strontium titanate thin films
The dielectric permittivity, dielectric quality factor ~inverse dielectric loss!, and lattice parameter of 140 nm sputtered SrTiO3 films were dependent on the oxygen partial pressure and total chamber pressure (O21Ar) during film growth. Films were grown at 25 and 75 mTorr ~mT! in an oxygen rich and oxygen deficient sputtering gas environment concurrently on ~100! SrTiO3 and ~111! Pt/~0001! Al2...
متن کاملINFLUENCE OF MGO ADDITION ON MICROSTRUCTURE AND PROPERTIES OF REACTION SINTERED ALUMINIUM TITANATE
Effect of MgO addition on reaction sintering of aluminium titanate was investigated using equimolar Al2O3 and TiO2 after firing the samples at 1400 C for four hours. Results showed that MgO addition enhanced the sintering process by magnesium aluminates formation, which led to lower porosity and improved densification of the samples. Physical and mechanical properties showed that samples contai...
