Abstract
Strontium barium niobate thin films with nominal composition corresponding to Sr0.30Ba0.70Nb2O6 (SBN30) were deposited onto Pt/Ti/SiO2/Si(100) substrate by ion beam sputter deposition (IBSD) technique. D–E hysteresis loops for Pt/SBN30/Pt capacitor samples were saturated after annealing treatment in air above 750°C, with remanent polarization (2Pr) value of about 22 μC/cm2 and coercive field (Ec) of about 128 kV/cm. Relative permittivity and leakage current characteristics were also determined from C–V and I–V measurements.
