Abstract

Changes in crystal structure and ferroelectric properties are investigated for (100)/(001)-oriented epitaxial PbTiO3 thin films grown on CaF2 substrates by metal organic chemical vapor deposition. In this work, PbTiO3 films, with thickness ranging from 60 to 2000 nm, presented volume fraction of (001)-oriented c-domain higher than 90%. Hence, the residual strain is smaller compared to films deposited on widely investigated SrTiO3 substrates. Additionally, more than 60 μC/cm2 remnant polarization is obtained for all film thickness ranges, and the estimated spontaneous polarization taking into account c-domain volume fraction is about 80 μC/cm2 regardless of film thickness, in good agreement with reported values for the single crystal.
