| Outline of Final Research Achievements |
In this study, impurity-doped diamonds were synthesized using high pressure and temperature synthesis method with pressure higher than that employed conventionally. Li- and Mg- doped diamonds were successfully prepared; however, to synthesize Li-doped diamond, Li-GIC (Graphite intercalation compound) is need as a starting material, while the synthesis of the Mg-doped diamond requires the use of a catalyst. In addition, the formation mechanism of Mg-doped diamond was investigated by in-situ X-ray diffraction experiment.
