Adsorption and diffusion of a silver atom and its cation on α-SiO2 (0 0 1): Comparison of a pure surface with a surface containing an Al defect

- Adsorption of Ag atom and cation on α-quartz (0 0 1) surfaces were modeled.
- The influence of Al-defect on the Ag adsorption was investigated.
- Cluster and periodic models were applied in this study.
- The energy barriers for Ag diffusion were calculated.
