Abstract

Ferroelectric thin films of Bi-containing layered perovskites such as Bi4Ti3O12, PbBi2Nb2O9 and SrBi2Nb2O9 have been processed by metal-organic decomposition (MOD) method. Films with random or c-orientation have been obtained via different heat treatment. Nucleation control has been identified as the mechanism for the texture evolution in these films. A strong polarization anisotropy has been observed which corresponds to the layered polarization in the crystal structure. The fatigue test results show that Ti seems to be a common species that exists in fatigue-prone ferroelectrics.
