dc.description.abstractFerroelectric polymorph of lead metaniobate (PbNb2O6) exhibits an orthorhombic structure, which is metastable at room temperature and can only be obtainable by quenching from high temperatures (∼1200°C). In this letter, we report a ferroelectric PbNb2O6 thin film doped with SrTiO3 (Pb0.95Sr0.05(Nb 2)0.98Ti0.05O6) with orthorhombic structure on Pt/Ti/Si substrate, which was prepared via a sol-gel route. The orthorhombic structure was developed at 900°C at a normal heating rate of 5°C/min and cooling rate of 10°C/min. The PbNb2O6 film exhibited a remanent polarization (Pr) of 12.3μC/cm 2 and a coercive field (Ec) of 39 kV/cm, respectively, when measured at an applied field of 143 kV/cm. The leakage current density was 1.02×10-5A/cm2 at 100 kV/cm. The room-temperature dielectric constant and dissipation factor was stable (∼325 and ∼1.5%, respectively) over a frequency range of 1 kHz to 1 MHz. © 2002 American Institute of Physics.
