Abstract

The effect of site selectivity on the ferroelectric polarization property was investigated in Dy-substituted Pb(Zr0.4Ti0.6)O 3 films prepared on (111)Pt/Ti/SiO2/(100)Si substrates by a chemical solution method. Dy ions were introduced, assuming Pb or Zr and Ti site substitutions in Pb(Zr0.40Ti0.60)O3 with x ranging from 0 to 0.06. Site occupation was determined by Raman spectroscopy. Dy ions selectively replaced the assumed sites at a low x value; however, these ions interdiffused to opposite sites at a high x value. Remnant polarization was enhanced when Dy ions selectivity substituted the Zr and Ti sites at a low x value, while it was contrarily degraded by Pb site substitution. These results provide useful guidelines for ferroelectric property improvement by ion substitution in Pb(Zr0.4Ti0.6)O3.
