Creation of Single Photon Centers in Diamond and SiC by Irradiation

Defect engineering using irradiation such as electrons and ion beams is one of the interesting topics. We study nitrogen-vacancy (NV) centers in diamonds, especially from the point of view of the creation methods of NV centers using accelerators. If 15N (natural abundance is only 0.37 %) ions are implanted into diamonds, we can distinguish NV centers created from implanted N (15N) or from residual N (14N) in diamond by measurement of optically detected magnet resonance (ODMR). In the presentation, the study of the creation yield of NV centers using 10 MeV-15N ion microbeams will be introduced. The coherence time (T2) of NV centers created in 12C enriched CVD diamonds by N implantation will be presented. Exploring of single photon centers in SiC will be also introduced.
