Oriented PbTiO3 films from metalorganic precursors

Abstract
PbTiO3 films on various substrates were prepared by a metalorganic decomposition process using a multilayer spinning technique. Films on LaAlO3 and MgO substrates were preferentially c‐axis oriented, and those on SrTiO3 have a completely c‐axis orientation. The mechanism leading to the orientation was discussed. Contrary to the c‐axis orientation, a‐axis orientation can be induced on otherwise random films if they were annealed under pressure.
