Abstract
The ion-surface scattering simulation SAFARI was modified to accommodate non-rectilinear targets. The basis for this change is discussed in the context of the computation time required for complex, nanostructured targets and the need to maintain the highly local molecular dynamics required for modeling low and hyperthermal energy ion trajectories. Results are presented for alkali ion scattering from noble metal targets (Au, Cu) and compared to experimental data. Scattering from a candidate nanostructured target, a stepped vicinal surface of Au, is also examined in detail and compared to an unstepped analogue to reveal step-dependent scattering features that could be measured in future experiments.
