The tetrahedrally coordinated structures (diamond cubic, zinc blende, and wurtzite) arise from a reorganization of the spherical "s'' and perpendicular "p'' atomic orbitals into a four-fold degenerate set of directional bonds with intrabond angles of 109.5°. This hybridization process promotes electrons from a low energy sp2 2 configuration to a

Both CBN and diamond are zinc blende sp3 hybrid cubic structure, both lattice constants are very similar, and the bonding bonds are basically the same. So, the similarity of the structures determines their similar performance.

Diamond is composed of carbon atoms. Zinc blende is composed of zinc atoms which are cations and sulfur atoms which are anions. The crystal structures of both diamond and zinc blende are face centered cubic lattice. Class 2: fcc, hcp, diamond, zinc blende, wurtzite, SiC, semiconductors . fcc.

The ratio of dangling bonds for the {100} and {111} planes of all diamond cubic and zinc blende structures is {100}:{111} = 2:1. Consider the diamond cubic, zinc blende, and wurtzite crystal structures. Give the lattice and the basis for each of these crystal structures. Predict the density of diamond, given that the equilibrium bond length for a C-C covalent bond is 0.154 nm.
