title = "Realizing strain enhanced dielectric properties in BaTiO3 films by liquid phase assisted growth",
abstract = "The addition of a liquid-forming flux to barium titanate thin films promotes densification and grain growth, improves nonlinear dielectric properties, and allows residual strain to be sustained in polycrystalline films without cracking at thicknesses relevant to device fabrication. Relative tuning, an excellent indicator of crystalline quality and an important material property for tunable microwave devices, increases from 20% to 70%. Films exhibit 0.15% residual differential thermal expansion mismatch strain, resulting in a shift to the paraelectric-ferroelectric phase transition of 50°C. This result is in excellent agreement with theory, demonstrating the ability to tune ferroic transitions without epitaxial approaches.",
