Strain-driven phase transitions and associated dielectric/piezoelectric anomalies in BiFeO3 thin films

Strain-driven phase transitions and associated dielectric/piezoelectric anomalies in BiFeO3 thin films

Strain-driven phase transitions and related intrinsic polarization, dielectric, and piezoelectric properties for single-domain films were studied for BiFeO3 using phenomenological Landau–Devonshire theory. A stable and mixed structure between tetragonal and rhombohedral-like (monoclinic) phases is p...
