| Research Abstract |
We investigated atomic and electronic structure using high spatial and temporal resolution core electron spectroscopy. During this project, we established accurate theoretical interpretation method of the spectrum (Micron 2010, PRB2011, JPC2011, Micron 2012 etc). Using those methods, we investigated Li-ion battery and other advanced materials. We found that the oxygen plays important role for the high capacity Li-ion battery material (APL 2014), and the motion of dislocation influences the electric properties very much (Sci. Rep. 2012). Furthermore, we established a powerful method to investigate the liquid with high spatial resolution (Sci. Rep. 2013).
