Figure 5
Alkaline displacement in KTP isostructures; the relative Δz (Å) shift is plotted versus the crystal temperature (K). The atomic size represents the occupancy parameter at each respective site. The two atoms at 1207 K show the likely split-cation positions for KTP at the ferroelectric-to-paraelectric phase transition.
