Numerical Study of the Thresholds of Sputtering of Metals during Bombardment with Low-Energy Ions

The transfer of energy from bombarding $${{{\text{K}}}^{ + }}$$ and $${\text{A}}{{{\text{r}}}^{ + }}$$ ions ( = 10–100 eV) to vanadium atoms is studied via molecular dynamics using the Vs potential. The threshold energy of vanadium sputtering is determined, and a numerical way of determining the thresholds of sputtering for solids is proposed.
