Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ). The position… Witryna28 sie 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.
