- Аннотация: The influence of the nearest atomic surrounding on the sputtering of atoms from the surface of (001) Au face in the <010> azimuthal direction toward the Wehner spot is examined. Using the molecular dynamics method, the ejection of an atom from a surface lattice site toward a lens consisting of two nearest neighbor surface atoms was calculated, taking into account varying numbers of surrounding atoms: 4 or 20 atoms from one top layer and 8 or 16 atoms from two top layers. Due to the above surface scattering effect, as the atomic surrounding expands, the sputtering yield increases by 17 to 37%. The addition of an atom behind the two-atom lens enables strong blocking, allowing sputtered atoms to be divided into two groups based on the initial polar angle ϑ0 with different emission mechanisms (two ejection cones). It is concluded that these mechanisms, absent in cascade theories of sputtering, must be taken into account for a correct analysis of single crystal sputtering.
