| Outline of Final Research Achievements |
The main achievement of this study is summarized in the following: (1) We have confirmed that the characteristic channeling patterns can be obtained from the variation of cathodoluminescence (CL) intensity under an electron incident-beam rocking, by using a transmission electron microscope equipped with a high-performance CL spectrometer. (2) We have developed a new quantification technique, based on the electron channeling effect, of the occupation sites of trace dopants in a complicated crystalline material.
