摘要

We prepared highly-aligned, biaxially textured Ba_xPb_(1-x)TiO_3 (PBT) on amorphous Si_3N_4 by using ion beam-assisted deposited (IBAD) MgO as a template layer. PBT was deposited on biaxially textured MgO using sol-gel synthesis, metallorganic chemical vapor deposition (MOCVD), and molecular beam epitaxy (MBE). The biaxial texture of the PBT was inherited from the MgO template. Reflection high-energy electron diffraction (RHEED) and cross section transmission electron microscopy (TEM) experiments suggest that exposure of the MgO template to atmospheric moisture before PBT heteroepitaxy resulted in a significant narrowing of the PBT in-plane orientation distribution. The microstructures of the biaxially textured PBT films were analyzed by x-ray diffraction (XRD), RHEED, and TEM. Dynamic contact mode electrostatic force microscopy polarization hysteresis loops confirmed that these films are ferroelectric.
