The lowest energy cleavage planes in silicon are the {111} planes. When a silicon single crystal is loaded to fracture, the cracks tend to initiate along a family of favoured crystallographic planes. In the case of plasma flow treatment of Si (100) surface, favoured cleavage planes are Si {111}, as are given in Fig. 2b.
