Abstract

Sr0.5Ba0.5Nb2O6 (SBN50) thin films have been prepared using aqueous organic gel method. The differences in the decomposition between Sr-Ba-Nb nitrate precursor solutions with different pH values were investigate. By heat treatment at 700 °C for 2 h, SBN thin films with smooth and crack-free surface were derived from the precursor solution of a lower pH=8. XRD patterns revealed the polycrystalline nature of the SBN thin films on Pt/Ti/SiO2/Si(100) substrates. Electric properties measurement indicated that the SBN films demonstrated a ferroelectric hysteresis loop. The remanent polarization (Pr) and coercive field (Ec) were 8.17 μC/cm2 and 16.9 kV/cm, respectively.
