We investigate the role of non-stoichiometry on the stabilization of the phase and physical properties in alloys and oxides. To that end, we employ state-of-art transmission electron microscopy techniques, and investigate both structural and functional materials through the imaging of nano-space inside. In particular, we carry out the imaging at the atomic level by using state-of-the-art electron microscopy techniques such as aberration-corrected microscopy, focal-series restoration (FSR), geometric phase analysis (GPA), and 3D tomography (TEMT). Based on the studies of crystallographic structures and microstructures with these methods, our research activities are ultimately targeted to understand the underlying nature, with which these complex structures are stabilized.
