Abstract
Nonlanthanoid-substituted In-x-Bi4Ti3O12 films with different indium contents at x=0, 0.2, 0.4, and 0.5, based upon the chemical formula of (Bi4−xInx)Ti3O12, were prepared at 600°C by chemical solution deposition. In-0.4-Bi4Ti3O12 films displayed a large remanent polarization of 57μC∕cm2, coercive field of 100KV∕cm, high nonvolatile polarization ⩾30μC∕cm2 after 1010 switching cycles, and low annealing temperature of 600°C. Good ferroelectric properties are mainly attributed to the partial substitution of the smaller-sized Ti4+ site by the larger-sized In3+ to enhance electrical polarization by a dimensional change of unit cell and to provide fatigue resistance by lattice distortion and chemical stabilization.
