| Outline of Final Research Achievements |
We discovered a phenomenon called negative contrast photoelectron diffraction in the energy-loss electron angular distribution which appears irrespective of polarization and type (light / electron) of the excitation source. By measuring photoelectron diffraction and energy-loss electron diffraction patterns in various crystal samples, we systematically investigated the relation between negative contrast photoelectron diffraction effect and escape depth, and clarified the mechanism of this phenomenon. Furthermore, we established a background removal method. The local atomic structure around dilute dopant atoms has been investigated. We also devised a new compact display type analyzer that efficiently measures such diffraction patterns and filed a patent application.
