Further technological developments now require materials with significantly higher performance and reliability. For electroceramic materials, such as multilayer ceramic capacitors and varistors, the grain size diminishing down to approximately 1 mm or less improves the properties of each grain and grain boundary further. To achieve this, it is crucial to clarify the atomic and electronic structures and develop a method to improve their properties. In our group, we investigate such atomic and electronic structures and their relationship with the material properties by combining electron energy loss spectroscopy (EELS), transmission electron microscopy (TEM), and first-principles calculations.
