Figure 3
Histograms of the Pb atom displacements in PZT (x = 0.48, 0.50, 0.55 and 0.60), shown on stereographic projections in panels (a)–(d) and in the form of polarization rotation angles in panels (e)–(h). The colour scheme in the top figures reflects the number of Pb atoms in the supercell, displaced in given crystallographic directions. The bottom figures are one-dimensional distribution profiles of the Pb atom displacement angles on the specific mirror planes away from the [001] direction.
