DFT Study of Cs/Sr/Ag Adsorption on Defective Matrix Graphite

Figure 4

Geometry structures of metal fission product adsorbed on matrix graphite surface: (a) perfect matrix graphite surface; (b) “bridge” and (c) “spiro” interstitial defects; and (d) single vacancy defect. Yellow balls represent the second layer of carbon atoms. Blue balls represent the metal fission products. The dash green lines represent the cross-sectional lines of charge density difference.
