Abstract Scope |
Charge neutral and inter coupled aliovalant substitutes in barium titanate are designed to function as dipolar pairs for generating novel relaxor-like ferroelectrics. In this work, a complex [Cu, 2Ta] dipole pair substituted BaTiO3 ceramics were manufactured with electronic grade precursor powders to show the unique electric and dielectric behaviors. Materials properties of crystal structure, microstructures, optical bandgaps, electric resistivity, and dielectric permittivity are reported for the series of Ba[Cu, 2Ta]xTi1-3xO3 with dipole concentration from x= 0 to x=0.025. A further investigation incorporating new simple material model (NSMM) provides the fundamental understanding for these complex dipole engineered dielectrics. |
