| Research Abstract |
In the vicinity of the lattice defects such as interface, grain boundary, surface, and dislocation, dopants or impurities are often segregated, and they change the macroscopic properties of the materials drastically. We call these dopants "function providing elements". The purpose of this study is to reveal the atomic and electronic structures around "function providing elements" by combining advanced transmission electron microscopy and first principles calculations, to understand their role on the properties quantitatively and to obtain the guideline to design new functional materials.
