HRTEM Observation on the diffusion process of ZnO·(ZnO)₅In₂O₃

Abstract

Homologous compound, (ZnO)_mIn₂O₃(m=integer), has very unique crystal strucure that is composed of the layers of In₂O₃, (InZn)O_2.5 and ZnO periodically stacking along the c-axis direction. In this study, we prepared the textured ceramics of (ZnO)₅In₂O₃ by the reactive templated grain growth (RTGG) technique, and investigated the diffusion proces of In ion on the ZnO block by HRTEM observation.
