Abstract
Sol-gel derived Bi4Ti3O12 thin films have been prepared on platinized Si wafers and fired to temperatures ranging from 550°C to 700°C. Excess Bi was incorporated in the precursor solutions to determine its effects on dielectric and ferroelectric properties. Multiple spincoating with an intermediate firing of 400°C between coatings was performed to obtain films up to 0.5 μm thick. Single phase Bi4Ti3 O12 films were obtained when fired at 600°C which exhibited a dielectric constant of 225
