Abstract

Lanthanum-modified lead-titanate (Pbo.85Lao.1Ti03) thin films were fabricated by rf magnetron sputtering on various kinds of substrates such as single-crystal MgO (100), r-plane sapphire and SI (100) with an MgO thin film layer. All the films were able to be evaluated using nickel alloy electrodes which possess low reactivity with PbO, excellent heat-resistance and oxidation-resistance. The quality of these films was affected by the kind of substrate and crystal orientation of nickel alloy electrode used. Furthermore, by controlling the crystal orientation of the alloy electrode, films on Si (100) with an MgO (100) layer showed good ferroelectricity.
