摘要
SrBi4Ti4O15 (SBTi) and CaBi4Ti4O15 (CBTi) dielectric films of Bismuth Layered Structure Dielectrics (BLSD) are examined as stacked-type dielectric capacitors for realizing excellent electric stability in capacitor device. It is revealed that the leakage current of the SBTi and CBTi is composed mainly from Schottky current for medium electric field range (about 100-350 kV/cm). The current is smaller by three order of magnitude than the BST single perovskite film, even with thinner thickness in the SBTi film. This indicates that the SBTi or CBTi film is effective for applying to high permittivity capacitor with the barium perovskite oxide family.
