摘要
Epitaxially grown Pb(Zr, Ti)O-3 (PZT, Pb: Zr: Ti = 1 : 0.52 : 0.48) thin films were prepared on Nb-doped SrTiO3 (100) substrates by dipping-pyrolysis process with metal naphthenates used as starting materials. The alignments of the films were investigated based on X-ray diffraction (XRD) theta-2 theta scans, beta scans (pole figures); and asymmetric omega-2 theta scans (reciprocal-space maps). Epitaxial films with smooth surfaces were obtained by heat treatment of prefired films at 600 degrees-750 degrees C; a film heat-treated at 750 degrees C showed the strongest peak intensities in the XRD theta-2 theta scans. These PZT films were found by reciprocal-space map analysis to consist of the c-axis-oriented tetragonal phase.
