Ferroelectric properties in all solution prepared Bi6Fe2Ti3O18/Ba0.92La0.08SnO3 thin films
In this paper, all solution processing is used to prepare both the transparent conducting Ba[Formula: see text]La[Formula: see text]SnO3 (BLSO) thin films as bottom electrodes and ferroelectric Bi6Fe2Ti3O[Formula: see text] (BFTO) thin films. The derived BFTO thin films are characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM). The derived thin film is polycrystalline with dense microstructures. The remnant polarization [Formula: see text] at the measurement frequency of 2 kHz can reach [Formula: see text] under the 500 kV/cm electric field and the coercive field [Formula: see text] is 410 kV/cm. The results will provide a feasible route to prepare BFTO thin films on transparent conducting bottom electrodes to realize multifunctionality.
