Wurtzite crystal structure zinc blende and diamond cubic
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. How does this compare with the measured density? Predict the density of ZnS, given that the equilibrium bond length for a Zn-S bond is 0.234 nm. How does your answer compare with the measured density of 4.10 g/cm^3?
