DFT Study of Cs/Sr/Ag Adsorption on Defective Matrix Graphite
The DOS for isolated Cs atom (dashed line) and Cs adsorbed on matrix graphite surface (solid line): (a) perfect matrix graphite surface; (b) “bridge” interstitial defect; (c) “spiro” interstitial defect; (d) single vacancy defect. The energy is relative to Fermi level (Ef) at E = 0 eV.
