| Outline of Final Research Achievements |
We have developed a new method to map electronic structure information in two dimensions with atomic resolution. This is based on the multi-frame method that integrates a large number of spectrum image data. For the first time, we have succeeded in atomic resolution mapping of oxygen holes in a high temperature superconductor using a new method. We have developed a momentum-selective high spatial resolution STEM-EELS method suitable for exploring the directionality of anisotropic electronic structures such as interfaces, and have succeeded in the measurement of inner-shell excitation spectra with atomic level resolution depending on the oxygen bonding direction in SrTiO3.
