| Research Abstract |
Stoichiometry in nano-scale, grain boundary area can determine microstructure and optical, conductive and mechanical properties of polycrystalline oxide compounds. The present study aims to establish controlling technique of grain boundary nano-stoichiometry in oxide compounds, and to investigate the effect of the nano-stoichiometry on various physical properties of the oxide compounds. Such experimental aspect will provide theoretical strategy of designing materials’ function based on the grain boundary nano-stoichiometry. For this purpose, it is necessary to develop techniques to control nanostructure of grain boundaries and to measure matter transport phenomena in oxide compounds. The present investigation will provide new aspects regarding the relationship between the nano-stoichiometry and matter transport phenomena in the oxide compounds.
