dcterms.abstract | Compositionally-graded (Ba[sub 1−x]Sr[sub x]dTiO₃ (BST) epitaxial thin films (with x decreasing from 0.25 to 0.0) were deposited by pulsed laser deposition on (100)LaAlO₃ (LAO) single-crystal substrates covered with a conductive La[sub 0.5]Sr[sub 0.5]CoO₃ (LSCO) layer as a bottom electrode. X-ray and electron diffraction patterns demonstrate that the entire graded film has a single-crystal cubic structure. The epitaxial relationship between BST, LSCO, and LAO can be described as (100)[sub BST] | - |

dcterms.abstract | [001][sub LSCO] | - |
dcterms.abstract | [001][sub LAO]. Cross-sectional transmission electron microscopy (TEM) images reveal that both the BST films and the LSCO bottom electrodes have sharp interfaces and overall uniform thickness across the entire specimen, and that they grow with a columnar structure. Planar TEM images show that the graded films exhibit granular and/or polyhedral morphologies with an average grain size of 50 nm. High-resolution TEM images reveal aligned rectangular-shaped voids in the graded BST film, with length size of 12-17 nm, and width of 5-8 nm along the <001> direction in the (100) plane. | - |
