Fig. 4

ad Schematic view of geometrical structures of damage Si/Ge superlattice after Si recoil events. The blue and green spheres represent the Si and Ge atoms, respectively. V X : X vacancy (X = Si or Ge); Xint: X interstitial (X = Si or Ge); X Y : X occupying the Y lattice site (X and Y = Si or Ge). The purple and red spheres represent the vacancy and interstitial defects, respectively
