| Outline of Final Research Achievements |
Regarding nanomaterials, effects of morphology and defects were investigated through the detailed structural analysis using pair distribution functions (PDFs). For the detailed structural analysis, diffractometry is the most commonly used technique but it can not be used for nanomaterials due to peak broadening based on limited size of crystallites. PDFs can be used for the analysis of crystals as well as nanocrystalline/amorphous materials.
In this research, first, feasibility and quality of data were investigated in order to know the limitation of current PDF technique. Then, analysis program for obtaining high quality of PDFs was developed (MaterialsPDF program). Finally, structures of several kinds of different nanomaterials were analyzed in detail. Through the term, the importance of detailed structural analysis of nanomaterials was clarified.
