- Abstract
- We report the growth of < 001 >-oriented Ba0.6Sr0.4TiO3 (BST) thin films on polycrystalline Ni-alloy tapes by pulsed laser deposition using biaxially oriented, ion-beam-assisted deposited (IBAD) MgO and gamma-Al2O3 buffer layers. Dielectric constant values of our BST films were up to similar to 85% of those in the epitaxial films prepared under similar conditions on single-crystal MgO substrates. No significant dispersion of the dielectric constant was observed for frequencies from 100 Hz to 1 MHz. These results demonstrate the versatility of using IBAD-textured MgO and gamma-Al2O3 buffer layers to integrate highly oriented good-quality BST films with nonsingle-crystalline substrates.
