Effect of layered structure on dielectric properties and energy storage density in xBa 0.7 Sr 0.3 TiO 3 -SrTiO 3 multilayer ceramics

xBa 0.7 Sr 0.3 TiO 3 -SrTiO 3 (BST-ST) multilayer ceramics with different BST layers (x=1, 3, 5) were designed and fabricated by lamination of Ba 0.7 Sr 0.3 TiO 3 (BST) and SrTiO 3 (ST) tapes. Dielectric and energy storage properties of the multilayer ceramics were investigated. BST-ST multilayer ceramics exhibited enhanced temperature- and frequency-stability of dielectric properties, accompanying high permittivity (~2000) and low dielectric loss ( 3 . These results indicate that BST-ST multilayer ceramics can be a favorable candidate for dielectric capacitor applications.
