Microstructure control in PZT/(111)-Pt heterostructures — •Salah Habouti1, Claus-Henning Solterbeck1, Vladimir Zaporojtchenko2, Franz Faupel2, and Mohammed Es-Souni11Institute for Materials and Surface Technology, University of Applied Sciences Kiel — 2Chair for Multicomponent Materials, Christian-Albrechts-Universtät zu Kiel

Investigations of film formation of Pb(Zr0.52Ti0.48)O3 (PZT) on Pt (111) shows that an interfacial intermetallic layer, PtxPb, forms as well under oxidizing and reducing atmosphere when the films are subjected to an intermediate annealing step at 550C. The formation of the intermetallic layer controls further crystallization and growth of the perovskite phase and confers to it a pronounced (111) texture at the fairly low annealing temperature of 600C. The crystallization of the morphotropic PZT phase is shown to initiate via incipient formations of a Ti-rich tetragonal phase at the interface with the intermetallic interfacial layer. The results are discussed in terms of thermodynamics and kinetic of phase formation.
