-Molecular-dynamics simulations for 1 keV Ar<sup>+</sup> → Cu(111) by Gerhard Betz; Animation by Michael Schmid. The simulation shows one arbitrary event with three ejected Cu atoms (one single atom, one dimer), other Ar<sup>+</sup> impact events can result in ejection of zero to many more Cu atoms.+Molecular-dynamics simulations for 1 keV Ar<sup>+</sup> → Cu(111) by Gerhard Betz; Animation by Michael Schmid. The simulation shows one arbitrary event with three ejected Cu atoms (one single atom, one dimer). Other Ar<sup>+</sup> impact events can result in ejection of zero to many more Cu atoms, with an average (sputter yield) around 2–3.
