•Local and average structure of NBT-BT at morphotropic phase boundary is reviewed.•Average structure of poled and unpoled samples of NBT-BT is discussed.•Structure-property relationships in NBT-BT and future directions are summarized.
Piezoelectric materials are increasingly being investigated for energy harvesting applications where (1−x)Na0.5Bi0.5TiO3–(x)BaTiO3 (NBT-BT) is an important lead-free piezoelectric material with potential to be used as an actuator in energy harvesting devices. Much effort has been put into modifying NBT-BT to tune the properties for specific applications, but there is currently no consensus regarding the structure-property relationships in this material, making targeted, rational design a major challenge. In this review, we will summarize the current body of knowledge of NBT-BT and discuss contradicting studies, unresolved problems, and future directions in the field.
Graphical abstractThis review of (1−x)Na0.5Bi0.5TiO3–(x)BaTiO3 (NBT-BT) summarizes the large body of literature regarding the structure-property relationships of this complex material. We highlight structural studies of the average and local structures of both unpoled and poled samples of NBT-BT at its morphotropic phase boundary and discuss them in context of the observed piezoelectric properties.Figure optionsDownload full-size imageDownload as PowerPoint slide
