摘要：
Non-c-axis-oriented SrBi2Ta2O9 (SBT) epitaxial thin films with (116)- and (103)-orientations have been grown on Nb-doped (011)- and (111)-oriented SrTiO3 (STO) substrates by pulsed laser deposition, respectively. Analyses of the X-ray diffraction pole figures revealed that the three-dimensional epitaxy orientation relationship SBT(001)parallel to STO(001); SBT[1 (1) over bar0]parallel to STO[110] is valid for both cases of SBT thin films, irrespective of STO orientations. The measured remanent polarizations (2P(r)) of (116)-oriented and (103)-oriented SBT films were 9.6 and 10.4 muC/cm(2), respectively, for a maximum applied electric field of 320 kV/cm. The dielectric constants of (116)- and (103)-oriented SBT were estimated as 155 and 189, respectively. (C) 2001 Elsevier Science Ltd. All rights reserved.
