(Color) Spatial distribution of Ti and Zr across the diagonal of the substrate (at. % by EDX).
Scanning electron micrographs of (a) cross section of the PZT layer. Transmission electron micrographs of (b) Zr:Ti ratio of 0.50:0.50 PZT.
(Color) XRD profiles of annealed PZT layer, diagonal across the substrate as a function of Zr:Ti ratio. The inset is an expanded view of profiles for the (110) peak.
Unit cell volume variation, diagonal across the wedges as a function of the position on substrate and hence Zr:Ti ratio.
Raman spectra of an annealed PZT layer across the substrate diagonal as a function of Zr:Ti ratio.
Typical hysteresis loops attained from points across the substrate diagonal.
