BiFeO3 and BiFe1-xWxO3 ($x = 0.005, 0.01, 0.02$) films were epitaxially deposited on LaNiO3(100)/Si substrates using a metal organic decomposition process. Well-saturated polarization--electric field hysteresis loops can be observed in all BiFe1-xWxO3 films owing to their leakage currents being lower than that of the BiFeO3 film. Additionally, the domains in BiFe0.995W0.005O3 and BiFe0.99W0.01O3 films can be uniformly switched using a piezoelectric-mode atomic force microscope (AFM) due to the efficient deaging effect of W6+. More importantly, the BiFe0.99W0.01O3 film exhibits the highest piezoelectric coefficient (${\sim}132$ pm/V) among all the films, making it promising for applications in high-temperature piezoelectric devices and AFM-tip-based data storage.
