| Outline of Final Research Achievements |
In recent years, dislocations have attracted much attention for their abilities to produce new functionalities based on unique atomic arrangements around them. However, the mechanisms of such functionalities had not yet been fully elucidated. In this study, the mechanisms by dislocations are investigated both experimentally and theoretically. First, we systematically investigated the dislocation-induced phenomena using first-principles calculations. By combining the obtained results with model experiments, it was found that the interaction with carriers has a significant effect on glide motions of dislocations. Theoretical analysis of the dislocation-induced changes in thermal conductivity revealed that thermal conductivity of materials may be controlled through microstructure of the dislocations.
