Lead-free ferroelectric BaTiO3 doped-(Na0.5Bi0.5)TiO3 thin films processed by pulsed laser deposition technique

► MPB lead free BNT-BT0.08 thin films were deposited on Pt/Si substrate, in optimized pulsed laser deposition conditions. ► Structural and morphological characteristics have been correlated with deposition process and target morphology. ► The BNT-BT0.08 thin film exhibits a well-defined ferroelectric hysteresis loop at room temperature. ► The leakage current density in BNT-BT0.08 thin film is relatively low. ► Local piezoelectric and ferroelectric responses in BNT-BT0.08 thin films, were identified.
