Table 1 Comparison of the contact of a diamond tip on various silicon crystal planes

From: Effect of crystal plane orientation on the friction-induced nanofabrication on monocrystalline silicon

Sample Si(100) Si(110) Si(111)
Contact area A (nm2) 8.86 × 103 7.61 × 103 7.17 × 103
Pressed volume V (nm3) 2.49 × 104 1.83 × 104 1.63 × 104
  1. The tip radius (R) is 500 nm, and the normal load (Fn) is 50 μN.
