| Research Abstract |
In this study, I developed new STEM imaging techniques based on the newly developed segmented-type detector for atomic resolution STEM. By using these new techniques, I show that we can directly observe light element atomic columns in ceramic interfaces with complex atomic structures simultaneously with heavy dopant elements. This means that we can fully determine atomic structure of ceramic interfaces through STEM observation. In addition, I could demonstrate that we can visualize local electric fields even at atomic dimensions by using the newly developed STEM. Moreover, we discovered very unique magnetic properties found at the dislocation cores of antiferromagnetic NiO. We could show that these properties are related to local nonstoichiometry of dislocation cores.
