| 英文摘要 | Lead-free piezoelectric single crystals of Fe-doped 0.95(Bi1/2Na1/2)TiO3-0.05BaTiO(3) are shown to combine multiple mechanisms for high strain and an effective piezoelectric coefficient of up to 3260pm/V. This is explained based on the analysis of superstructure reflections from diffuse synchrotron x-ray scattering. It depends on three factors: (1) the stabilization of a local tetragonal structure by (Fe'-)(center dot) defect dipoles, (2) the reversible creation of a morphotropic phase boundary under field, and (3) the field-induced reversible transition between a short-range ordered relaxor and a long-range ordered ferroelectric state. [GRAPHICS] . IMPACT STATEMENTThe observation that a combination of three different physical mechanisms produces unprecedently high piezoelectric response in a lead-free piezoelectric presents a breakthrough in the fundamental understanding of optimizing piezoelectric properties. |
