dc.description.abstractThe authors report on an approach to establish intrinsic polarization properties in bismuth-layered ferroelectric films by piezoelectric coefficient and soft-mode spectroscopy, as well as by a direct polarization-electric field hysteresis. In epitaxially grown (Bi4−xNdx)Ti3O12 (0⩽x⩽0.73)films, they show that these complementary characterizations can phenomenologically and thermodynamically represent the intrinsic polarization states in (Bi4−xNdx)Ti3O12films, and the intrinsic Ps of 67μC/cm2 is estimated for pure Bi4Ti3O12, superior to 50μC/cm2 in bulk single crystal. Their results provide a pathway to draw full potential in ferroelectric thin films.en
