Sol-gel processing of bismuth strontium tantalate thin films

The synthesis of bismuth strontium tantalate thin films by alkoxide route and their ferroelectric properties were studied. It was found that single phase ferroelectric films with the thickness of 0.4-0.5 µm could be formed by four repeated cycles of deposition of 2-ethylhexanoic acid solution of metal alkoxides on Si-SiO2-Ti-Pt wafers followed by annealing in the temperature range of 700-750°C for 30 min after each deposition. The films showed remanent polarization ranging from 3.5 to 4.0 µC/cm2 and coercieve voltage 1.5-2.0 V
