Abstract

Single-crystal, single-phase Pb (Zrx Ti1-x) O3 films (x=0-0.4) were grown on (001) SrTi O3 and SrTiO3:Nb substrates by molecular beam epitaxy. Layer-by-layer growth of the Pb (Zr,Ti) O3 films was achieved by using PbTi O3 buffer layers between the SrTi O3 substrates and the Pb (Zr,Ti) O3 films. The layers with low Zr content showed high crystallinity with full width at half maximum of ω -rocking curves as low as 4 arc min, whereas increase in Zr concentration led to pronounced angular broadening. The Pb Zr0.07 Ti0.93 O3 films exhibited remanent polarization as high as 83 μC cm2, but local areas suffered from nonuniform leakage current.
