Origin of large electrostrain in Sn4+ doped Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 ceramics
Source abstract
Abstract
Abstract A relatively large bipolar strain of 0.23 % was recently reported in 3 % Sn4+ doped (BaTi0.8Zr0.2)O3-x (Ba0.7Ca0.3)TiO3 (BZT-xBCT) ceramics under a field of 20 kV/cm. This strain is 53 % higher than that in BZT-50BCT (0.15 % at 20 kV/cm). To systematically study the mechanism and origin of the large electrostrain enhancement in Sn4+ doped BZT-53.3BCT, we develop a parameterized Landau free energy model and perform phase field simulations. Our results indicate that the softening of the elastic modulus C ′ = C 11 − C 12 accompanied by the reduction of anisotropy energy due to the 3 % Sn4+ doping is primarily responsible for the large electrostrain enhancement.
