Fig. 4.15 compares the simulated vacancy concentration profiles in silicon and in germanium associated with the 20keV boron implantations shown in Fig. 4.14. The vacancy maximum is not at the wafer surface, since the electronic stopping process dominates at high initial energies of the ions, when they enter the crystal. A boron ion enters most likely a channel at the surface and despite of the
