Outline of Final Research Achievements

This research project intends to the realization of electronic state mapping of oxygen with atomic resolution using scanning transmission electron microscopy (STEM) and electron energy loss spectroscopy (EELS).First of all, we established a method for measuring high signal-to-noise ratio spectrum from individual atomic site without damage.Then, we succeeded for the first time in atomic-resolution two-dimensional mapping of holes in cuprate superconductors using an advanced technique. In addition, we have demonstrated the anisotropic chemical bond related to the difference between px and py orbitals was observed with atomic resolution.The results enables atomic-resolution anisotropic spectroscopy and is expected to give complementary information to the polarization-dependent X-ray absorption spectroscopy (XAS) which is widely used.
