چکیده انگلیسی
The Sr and Ca added to BaTiO3 in order to shift transition temperature near room temperature. The donor (Yb2O3) and acceptor (MnCO3) impurities were added to the (Ba,Sr,Ca)TiO3 powder for the improvement of structural and electrical properties. The (Ba,Sr,Ca)TiO3 powder was made by sol–gel method and the thick films were fabricated by screen-printing. We fabricated array type thick films. The 1 mm × 3 mm array thick films were arranged 2 × 8. Relative dielectric constant and dielectric loss of Yb2O3 0.1 mol% doped (Ba,Sr,Ca)TiO3 array thick film were 1068 and 2.8%, respectively at Curie temperature, 44 °C. Pyroelectric coefficient and F.M.D* showed 21.7 × 10−9 C/cm2 K and 3.2 × 10−9 C cm/J, respectively.
