Figure 7From: Effect of crystal plane orientation on the friction-induced nanofabrication on monocrystalline siliconConfiguration of Si-Si covalent bonds on different planes of monocrystalline silicon. (a) Si(100); (b) Si(110) and (c) Si(111). The dangling bonds were indicated by dotted lines. Some covalent bonds that inhibit on one atom are partly showed.Back to article page
