Large High-Temperature Piezoelectric Response of Lead-free BiFeO₃-BaTiO₃ Originating from Relaxor Disorder.

ABSTRACT: To date, no piezoelectric material system has been developed that would match the piezoelectric performance of the group of lead-based relaxor ferroelectrics, such as Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ (PMN-PT). In the quest to find alternatives, continuous efforts have been made to understand the complex microscopic origins leading to the large macroscopic piezoelectric response of PMN-PT and similar lead-based perovskites with relaxor characteristics. Despite significant advances, it is still unclear whether those concepts can be efficiently used to develop lead-free relaxor ferroelectric alternatives. Here, a large piezoelectric response of BiFeO₃-BaTiO₃ (BFO-BTO) ceramics is reported, characterized by a d₃₃ coefficient o
