چکیده انگلیسی
Thin films of ferroelectric calcium barium niobate, CaxBa1âxNb2O6, are deposited on MgO(1Â 0Â 0) substrates by pulsed laser deposition. The microstructure of the films is investigated by means of conventional and high-resolution transmission electron microscopy. The observation of plan-view and cross-sectional samples shows that the films are polycrystalline. The grains orient with their c-axis parallel to the normal of the film surface. Two sets of preferential in-plane crystallographic relationships are determined as ã1Â 1Â 0ãCBN//ã4Â 1Â 0ãMgO and ã1Â 0Â 0ãCBN//ã3Â 1Â 0ãMgO. Chemical reactions occur at the interface between the film and the MgO substrate, leading to the formation of two phases, corundum-type Mg4Nb2O9 and pseudobrookite-type Mg5Nb4O15.
