抄録

Thin films of solid solution of SrBi2(Ta0.7Nb0.3)2O9-Bi 3TaTiO9 [(1 - x)SBT-xBTT] were prepared on (1 1 1)Pt/Ti/SiO2/Si substrates at 650°C by metal organic chemical vapor deposition (MOCVD). Solid solution composition was ascertained by linear lattice parameter change with composition following Vegard's law. Films showed a strong (1 0 3) orientation. Dielectric constant linearly decreased with increasing x and the remnant polarization took a maximum value at x = 0.3 and was almost the same as Sr0.8Bi2.2(Ta0.7Nb0.3)2O 9 film. Moreover, Curie temperature of this material with x = 0.3 was 440°C and was almost the same as that of Sr0.8Bi2.2(Ta0.7Nb0.3)2O 9.
