Abstract:
Samples of BaTiO$_3$/(Ba$_{1-x}$Sr$_x$)TiO$_3$ (BT/BST-$x$) superlattices have been studied using X-ray diffraction analysis. A complete parallel orientation of all the studied films and the substrate has been revealed, and the modulation periods $\Lambda$ of the superlattices, the parameters of the unit cell averaged over the $\Lambda$ period, and the parameters of individual components of the superlattices have been determined.
