摘要
Lead-rich intermediate phases, in particular Pt5-7Pb and PbO, are found to form on Pt(lll) atop Ti-buffered Si substrates prior to formation of Pb(Zr1-xTix)O-3 (PZT) thin films. Pt5-7Pb is a [111] textured transient intermetallic phase that nucleates PZT[111] texture. PbO is a [001] textured layer compound that nucleates PZT[100] texture. The formation conditions and lattice matching of these intermediate phases have been examined. The presence of other possible intermediate phases, such as pyrochlore and Zr and Ti-rich phases, has also been investigated but found unrelated to the texture selection of perovskite PZT.
