Answer #1

1. A Unit Cell Has 18 Silicons Atoms 2. Weak Bonding Along Cleavage Planes 3.Wafer Splits into 4 or 6 Wedge Shaped Fragments 4. Miller Indices is Used to Assign to Each Possible Plane Passing Through the Crystal Lattice.

The unit cell for graphene is a two-dimensional rhombus according to the figure shown*. The result is that two atoms are contained per unit cell. The upper right structure actually appearing in graphite, stacked layers of graphene.
