WebJul 4, 2024 · Crystalline solids, or crystals, have distinctive internal structures that in turn lead to distinctive flat surfaces, or faces. The faces intersect at angles that are characteristic of the substance. When exposed to x-rays, each structure also produces a distinctive pattern that can be used to identify the material. WebAug 28, 2024 · All the atoms in a zinc blende structure are 4-coordinate. The zinc blende unit cell is shown in Figure 7.1.9. A number of inter-atomic distances may be calculated for any material with a zinc blende unit cell using the lattice parameter (a). Zn − S = a√3 4 ≈ 0.422a. Zn − Zn = S − S = a √2 ≈ 0.707 a.
