Electromechanical properties of sodium bismuth titanate thin films

open access: yesThin 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.

Investigation of Ga Doping for Non-stoichiometric Sodium Bismuth Titanate Ceramics [PDF]

open access: yesJournal of Materials Science: Materials in Electronics, 2021
Abstract The electrical performance of Ga3+ doping Na0.5Bi0.5TiO3-based oxygen ion conductor was studied. The Na0.52Bi0.47Ti1−xGaxO3−δ (x = 0, 0.01, 0.015, 0.02) samples were fabricated by the means of traditional solid-state reaction. The results of AC impedance measurement show that the bulk conductivity of Na0.52Bi0.47Ti1−xGaxO3−δ samples ...
