Abstract

Portions of the same epitaxial (103)-oriented SrBi2Nb2O9 film grown on (111) SrTiO3 for which we recently reported the highest remanent polarization (Pr) ever achieved in SrBi2Nb2O9 (or SrBi2Ta2O9) films, i.e., Pr = 15.7 μC/cm2, have been characterized microstructurally by plan-view and cross-sectional transmission electron microscopy (TEM) along three orthogonal viewing directions. SrBi2Nb2O9 grows with its c axis tilted 57° from the substrate surface normal in a three-fold twin structure about the substrate [111], with the growth twins' c axes nominally aligned with the three 〈100〉 SrTiO3 directions. (103) SrBi2Nb2O9 films with and without an underlying epitaxial SrRuO3 bottom electrode have been studied. Dark-field TEM imaging over a 12 μm2 area shows no evidence of second phases (crystalline or amorphous). A high density of out-of-phase boundaries exists in the films.

20. Two types of twins are present in these epitaxial (103) SrBi2Nb2O9 films: (1) twins that arise during growth due to the (111) SrTiO3 substrate surface and (2) twins that occur as the SrBi2Nb2O9 transforms from tetragonal to orthorhombic as it is cooled. We refer to the former as growth twins and the latter as transformation twins. To image transformation twins, i.e., see the ferroelectric domains, it is necessary to distinguish between the a and b axes of SrBi2Nb2O9. In this article we have not made any such distinction in either xray diffraction or TEM characterization, and have imaged only the three growthtwin variants.Google Scholar
21. In addition to the hkl SrBi2Nb2O9 indices given, khl SrBi2Nb2O9 indices are also implied. The latter indices are omitted for clarity, but arise because of transformation twinning. The hkl SrBi2Nb2O9 indices given are for the SrBi2Nb2O9 transformation twins having their a axis 57° out of the plane of the substrate. However, the films also contain transformation twins in which the a axis of the SrBi2Nb2O9 lies in the plane of the substrate and the b lies 57° out of the substrate plane.Google Scholar
