Here we present molecular dynamics simulation results obtained using embedded atom potentials for Cu/Cu(100) growth carried out in order to measure the strength of the steering effect due to short-range interactions. Our results indicate that even at normal incidence, the short-range attraction can lead to a significant uphill current which can significantly increase the selected mound angle and surface roughness. The results of kinetic Monte Carlo simulation of Cu/Cu(100) growth with steering effects included are also presented and compared with recent experiments. |  | View paper | | ISBN: | 0-9708275-6-3 |
