The 4H refers to the fact that there are 4 CSi dimers in a hexagonal unit cell. Zincblende is denoted 3C, and wurtzite is 2H. This structure is related to the α–La

Zinc blende (zb) and wurtzite (wz) structure of cadmium sulfide (CdS) are analyzed using density functional theory within local density approximation (LDA), generalized gradient approximation (GGA), Hubbard correction (GGA + U), and hybrid functional approximation (PBE0 or HSE06). To assure the accuracy of calculation, the convergence test of total energy with respect to 2008-05-01 · (a) The unit cell of CdTe in cubic zinc-blende phase (space group F43m) and (b) the hexagonal wurzite phase (space group P63mc). However, the theoretical aspects of optical properties of cadmium telluride particularly in the hexagonal wurzite phase have been relatively rarely studied, most published data are related to the cubic zinc-blende phase. The zinc blende structure derives from the fcc structure by stacking two fcc unit cells into one another, offset by a quarter of a spatial diagonal. One of these identical sub-lattices is populated by cations (zinc in the case of the type mineral), the other by anions (sulphur).

The primitive GaN unit cell contains 4 atoms, in the case of the wurtzite structure (space group ), and 2 atoms, in the case of the zinc blende structure (space group ). There are several equivalent ways to define the unit cells. For the purposes of these initial calculations we will define the structures as follows:

The zinc blend structure is cubic. The unit cell may be described as a face-centred sulphide ion sub-lattice with zinc ions in the centres of alternating mini cubes made by partitioning the main cube into 8 equal parts.

Zinc sulfide crystallizes in a Face-Centered Cubic unit cell (FCC) having an edge length of 5.409 AngstromsSulfide anions have FOUR neighbors of opposite charge arranged at vertices of a tetrahedron.

The customary unit cell is chosen as to make the symmetry of the system apparent. So for fcc lattices we use a cubic unit cell which consists of 4 primitive unit cells (and therefore contains 4 atoms in copper and 8 in diamond or zincblende).
