Abstract
Pb(Zr 0.5 Ti 0.5 )O 3 thin films 25 nm in thickness were grown on LaNiO3/Pt/Ti buffered Si substrates at 600 °C by metalorganic chemical vapor deposition. P–E studies showed a remanent polarization value of 8 μC/cm2 with a coercive field of 200 kV/cm. In polarization fatigue studies, these films only showed slight degradation in remanent polarization up to 4×108 cycles (±3 V oscillation) before breakdown. Moreover, the effect of space charge on the C–V behavior of these films was illustrated I–V characteristics of these films were also described.
