Abstract

Synthetic single crystal diamonds are irradiated with 100 MeV carbon-ion and characterized by measurements of the X-ray lattice parameter and diffuse scattering (XDS) at room temperature. The lattice parameter increases with the ion fluence. The intensity of XDS diffuses asymmetrically to form a streak along the [-1 0 0] direction parallel to the reciprocal lattice vector. These results suggest that interstitial atoms induced by irradiation aggregate to form dislocation loop on the (1 0 0) plane in the synthetic single crystal diamonds. The results are similar to the XDS of boron-doped single crystal diamond suggesting that boron atoms are likely to form precipitates on the (1 0 0) plane.
