Electromechanical properties of sodium bismuth titanate thin films

Thin Solid Films, 2022
Lead-free piezoelectric sodium bismuth titanate (BNT) films are promising candidates for actuators applications as an alternative to lead zirconate titanate films. We focused in this work on the growth and characteristics of BNT films deposited by sputtering on silicon substrates with LaNiO3 electrodes.
