This is a binary phase (ME) and is named after its archetype, a common mineral form of zinc sulfide (ZnS). As with the diamond lattice, zinc blende consists of the two interpenetrating fcc lattices.

In this case (a homework problem I'm stuck on) the atoms are In and SB, but generally speaking Zinc blende (sphalerite) has 140 atoms and 308 bonds. This crystal lattice semiconductor structure is also essentially the same as that found in indium phosphide & diamond.. Click here to see our entire range of Orbit Molecular Model Kits or you can augment … Zinc Blende is the name given to the mineral ZnS. It has a cubic close packed (face centred) array of S and the Zn(II) sit in tetrahedral (1/2 occupied) sites in the lattice, giving a Unit Cell with 8 Zn and 16 S's. In this video I introduce the zinc sulfide crystal structure. This structure is similar to diamond cubic in terms of atom positions and is often helpful in The lattice constant of cubic MnS with rock salt structure is 5.20 A, whilst the lattice constant of metastable cubic MnS with zinc blende structure is 5.60 ,~,, the latter being as dense as the wurtzite phase used in our experiments. The entire structure rests on three assumptions: (1) that equation (5) holds, (2) that the 100 per cent ionic zinc blende lattice is non-existent because C^ = C^, and (3) that the theory for polar lattices holds. and zinc blende lattice is small [11]: DE W-ZB ¼ 18.41meV/atom for AlN, DE W-ZB ¼ 11.44meV/atom for InN, and DE W-ZB ¼ 9.88meV/atom for GaN. Wurtzite form is energetically preferable for all three nitrides compared to zinc blende, although the energy difference is small.

There is one thing common in zinc blende and wurtzite lattices; both have tetrahederal coordination. Structural and elastic properties of InN1-xBix alloys in both zinc-blende and wurtzite phases are studied by using first-principle calculations. Two different Bi-atom arrangements of uniform and clustered configurations have been considered for x = 0.25, 0.5, and 0.75. It is found that clustered configuration has a significant effect on lattice parameters of wurtzite InN1-xBix alloys.
