Abstract
⺠An angular window of 65-82.5°, in terms of ion incident angle, was chosen for this study. ⺠Parallel-mode ripple formation is observed in the angular window of 65-67°. whereas unusual patterns evolve over the angular window of 70-77.5°. ⺠Perpendicular mode ripples are formed at an incident angle of 80°. ⺠We showed that the transition from parallel- to perpendicular-mode ripples is not a sharp one. ⺠The observed patterns are attributed to surface confined viscous flow and sputter erosion under ion bombardment.
