| Abstract Scope |
In this talk, we will first review a series of earlier studies on electric field effects on microstructural evolution in ZnO. Specifically, we discovered an electrochemically induced grain boundary disorder-to-order transition to trigger abnormal grain growth in Bi2O3-doped ZnO [Nature Communications 12:2374 (2021)]. We further studied the electric field-induced microstructural evolution in polycrystalline Bi2O3-doped ZnO in presence of a secondary liquid phase [Adv. Eng. Mater. 25:2201767 (2023)]. Moreover, we showed that applied electric fields can induce grain boundary oxidation transitions near the anode to create continuously graded microstructures in undoped ZnO [Materials Today 73:66 (2024)]. Ongoing and unpublished results in electric field effects on microstructural evolution in SrTiO3 and BaTiO3 based systems will also be discussed. |
