Abstract

La-substituted Bi₄Ti₃O₁₂ (BLT) epitaxial ferroelectric thin films having a reduced number of azimuthal domains were grown by pulsed laser deposition on offcut yttria-stabilized zirconia (YSZ) single crystal substrates. Crystallographic structure and electrical properties of the films grown on offcut YSZ(100) substrates with an offcut angle of 5° have been investigated. BLT films grown on [011] offcut YSZ(100) substrates covered with SrRuO₃(110) electrode layers showed a considerably higher reduction of the number of azimuthal domains than those grown on SrRuO ₃(110) electrode layers on [001] offcut YSZ. Higher remanent polarization values were measured in BLT films on [011] offcut YSZ(100) substrates, compared to BLT films grown on [001] offcut or exactly cut ones, most probably due to the reduced number of azimuthal domain boundaries.
