Starting from a theory recently proposed by Kahng et al. that explains the
formation of ordered dots by ion sputtering under normal ion incidence, it
was demonstrated that extending this theory to ion sputtering under oblique
ion incidence with simultaneous sample rotation offers the self-organized
formation of dots by ion sputtering for a large variety of different ion/ma
terial combinations. While for sputtering under normal incidence the shape
of the collision cascade must be anisotropic, where the lateral straggling
exceeds the longitudinal straggling, this constraint is not necessary under
oblique incidence.
