LGD Generalized Boundary Conditions BST Polydomain Phase Diagrams Data

This data package contains the data used in the derivation of the strain-temperature phase diagrams of epitaxial barium strontium titanate solid solutions. The data contains the description of the phase boundaries across multiple chemical compositions of the solid solution. The package also includes the ferroelectric equilibrium states (polarization, domain wall orientation, domain volume fractions) as a function of the biaxial epitaxial misfit strain, temperature, chemical composition of the solid solution. The equilibrium states are provided for the single-domain and polydomain/heterophase configurations of the material. The equilibrium states are used in the definition of the phase diagrams and the corresponding phase boundaries included in the dataset.
