摘要
The influence of the Pt bottom electrode orientation on the growth of SrBi2Ta2O9 (SBT) films was elucidated in terms of the atomic matching at the SBT/Pt interfaces. A highly c-axis oriented SET film was grown on the Pt (001) plane since the SET (00l) plane conjugates well with the Pt (001) plane from a crystallographic point of view. Both the strong (105)(tet) and (110)(tet) SBT peaks were found in the x-ray diffraction profile when the SET film was grown on the Pt (111) surface. It was found that not a single SET plane can match with the whole Pt (111) plane due to the appreciably different atomic configurations. The cross-sectional transmission electron microscopy image revealed that the SBT/Pt interface was structurally stable after heat treatment at 750 degrees C. (C) 1998 American Institute of Physics.
