Abstract
Fabrication of ferroelectric Bi4Ti3O12 thin films was carried out by spin-coating pyrolysis process of metal naphthenates. The films were finally sintered at 800 °C for 30 min in O2 gas with the pressures ranging from 0.1 to 0.4 MPa. In any conditions, ferroelectric Bi4Ti3O12 thin films with complete c-axis orientation were obtained. Remanent polarizations of the films were improved with increasing O2 gas pressure in sintering while coercive fields were constant. The Bi4Ti3O12 thin film sintered at the O2 gas pressure of 0.4 MPa exhibited good ferroelectric properties: the remanent polarization of 2.1 μC/cm2 and the coercive field of 66 kV/cm. The remanent polarization of the film sintered at 0.4 MPa was observed to be 95% of the initial value after the polarization reversal of 1×109 cycles while that of the film sintered at 0.1 MPa was reduced to about half of the initial one after 1×107 cycles. Sintering at high O2 gas pressure had a great influence on the improvement of fatigue properties of ferroelectric Bi4Ti3O12 thin films.
