Defect structures and surface morphologies after scratching and retraction under D1 and D2 (a,b,c,d). Defect structures after scratching and retraction under the scratching depths D1 and D2, respectively. Atoms are colored according to their BAD values, and FCC atoms are not shown. (e,f,g,h) Surface morphologies after scratching and retraction under the scratching depths D1 and D2, respectively. Atoms are colored according to their heights in Y direction.
