Figure 1From: Ion beam-generated surface ripples: new insight in the underlying mechanismSchematic view of 50 keV Ar+ion beam irradiation. For first stage (to prepare two deferent depth locations of a/c interface) at an angle of (a) 60° and (b) 0°, with respect to surface normal; second stage irradiation (for fabrication of ripples) at an angle of 60° named as (c) set A and (d) set B.Back to article page
