Abstract	The lead-free Na0.5Bi0.5TiO3-K0.5Bi0.5TiO3-SrTiO3 (BNT-BKT-ST) and (La, Fe)-codoped Na0.5Bi0.5TiO3-K0.5Bi0.5TiO3-SrTiO3 (BNT-BKT-ST-LaFe) thin films were deposited on Pt/Ti/SiO2/Si substrates by the sol-gel method. Both the BNT-BKT-ST and BNT-BKT-ST-LaFe thin films exhibit pseudo-cubic perovskite structure and uniform grain size. The leakage current density of BNT-BKT-ST-LaFe thin film at 400 kV/cm is reduced by approximately two orders of magnitude compared with BNT-BKT-ST thin film. Enhanced ferroelectric property is achieved in BNT-BKT-ST-LaFe film with a large remanent polarization of 13 μC/cm². At the same time, the BNT-BKT-ST-LaFe film also exhibits a large dielectric constant of 420 and small dielectric loss of 0.055 at 100 kHz. These results indicate that the (La, Fe)-codoped BNT-BKT-ST thin film is a promising candidate in lead-free ferroelectric materials.
