| Abstract Scope |
Electronic devices like capacitors, sensors, transducers, filters, resonators, actuators, etc. can be made more robust and efficient using enhanced relaxor and relaxor-like ferroelectric material properties. Previous material studies based on morphotropic phase boundary (MPB) and polymorphic phase boundary (PPB) have yielded classic relaxor materials, including PMN-PT; however for environmental reasons, Pb based materials need be replaced without reducing a possibly enhancing device properties. Dilute, low concentration, dipole-pair engineering is becoming a novel route for designing relaxor-like ferroelectric materials. In this work, microstructural, electric, dielectric, and optical properties of the [Sc, Ta] dipole-pair substituted BaTiO<sub>3</sub> ceramics are investigated and the unique relaxor-like behavior of these materials are reported. |
