摘要
SIMS experiments using cluster ions show promising results in de-sorbing intact large molecules from the surface of various materials. The optimum size, shape and energy of the clusters and the material surface has not been studied in any detail. Presented here are the results of a comparative study of gold and carbon clusters of similar total mass and energy, in particular Au(4) and C(60) clusters and Aug and C(100) clusters are compared and contrasted. The behaviour of the graphite lattice, used as the target substrate material, during the impacts is studied in detail and differences in depth of penetration, damage and energy propagation are reported.
