Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of anions. In both structures, the cations occupy one of the two types of tetrahedral holes present. In either structure, the nearest neighbor connections are similar, but the distances and angles to further neighbors differs.

The zinc blende ZnO structure is metastable and can be stabilized only by heteroepitaxial growth on cubic substrates, such as ZnS [5], GaAs/ZnS [6], and Pt/Ti/SiO 2/Si [7], reflecting topological compatibility to overcome the intrinsic tendency of forming wurtzite phase. In the case of highly mismatched substrates,
If the density is 3.02 g/cm3 and the lattice parameter is 0.59583 nm, determine the number of Schottky defects (a) per unit cell; and (b) per cubic centimeter. All the atoms in a zinc blende structure are 4-coordinate. The zinc blende unit cell is shown in Figure 9.
