Raman Spectroscopy for Quantitative Analysis of Point Defects and Defect Clusters in Irradiated Graphite
Figure 15
Nucleation and growth of dislocation dipole. Divacancies formed by knock-ons, occurring at sites close to single vacancies, reconstruct to eliminate dangling bonds as shown in the left-hand side area. The reconstructed divacancies are the nucleus of the dislocation dipoles. Dislocation dipoles can grow by successive knock-ons close to the ends of dislocation dipoles as shown in the right-hand side area.
