Abstract

High-temperature fluorite structure Bi₂O₃ is a well-known solid electrolyte due to its high oxygen ion conductivity. The stabilization of cubic Bi₂O₃ may be enhanced by adding rare earth oxide. It was thought that phase transformation was caused by the presence of oxygen vacancies. In this study, Bi₂O₃ thin film was prepared by oxidation on the electroplated Bi. The effect of applied voltage on crystallization of metallic Bi thin film was investigated. The oxidation reaction of Bi with various crystalline orientations is discussed. Two preferred orientations, (102) and (202), appeared in XRD. After oxidation, β-Bi₂O₃ and α-Bi₂O₃ appeared due to the specific atomic configurations of (102) and (202). The microstructure observed by SEM showed microcracks due to lattice expansion from phase transformation. The volume changes from rhombohedral Bi to β-Bi ₂O₃ and α-Bi₂O₃ were estimated to be 16.73 and 19.14%.
