FIG. 1.

Thermodynamic calculations of polarization variation with PTO volume fraction in (PTO)/(BTO) superlattices under different temperatures (a), and the polarization and tetragonality enhancement as a function of mismatch strain in individual BTO and PTO films (b).

FIG. 2.

Tetragonality variation with PTO volume fraction at different temperatures (a). The dashed-dotted black line describes the variation of , and the dash purple line represents the volume value at which the tetragonality reaches minimum at room temperature. A and B are the points at which purple line crosses the and tetragonality variation lines at room temperature, respectively. (b) Plots of polarization and tetragonality versus temperature for individual BTO and PTO films on STO substrates.

FIG. 3.

Domain morphology of a (PTO)/(BTO) superlattice obtained through a phase field simulation at room temperature. The two colors (purple and grey) in the superlattice represent -domains with up and down polarization dipoles, respectively.
