Dielectric properties of compositionally graded Ba1−xLaxTi1−x/4O3 thick films
چکیده انگلیسی
Compositionally graded thick films based on lanthanum-substituted barium titanate solid solutions Ba1−xLaxTi1−x/4O3 (BLT, x=0.02, 0.04, 0.06) are prepared by tape casting and their phase structures, surface morphologies, dielectric and tunability properties have been examined. Compared with single-layered BLT film, compositionally graded BLT02/04/06 film with three-layered sandwich-structure has better temperature stability in dielectric and tunability properties. Curie peak is broadened, dielectric loss is reduced, and more importantly, it has moderate permittivity and high tunability (>35%) in a temperature range of 25-75 °C, which is beneficial for practical applications of tunable devices.
