The equilibrium lattice constant, molecular and crystal densities, bond length, the independent elastic constants, bulk 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.

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.

both structures. Stick-and-ball stacking models for 2H wurtzitic and 3C zinc blende polytypes of ZnO crystals are shown in Figure 1.6. The wurtzite and zinc blende structures differ only in the bond angle of the second-nearest neighbors and, therefore, in the stacking sequence of close-packed diatomic planes.

Two different Bi-atom arrangements of uniform and clustered configurations have been considered for x = 0.25, 0.5, and 0.75.

Sphalerite can have Spinel Law twins, where the twin axis is [111]. 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. The display shows an idealised unit cell (Space group 216 F-43m). Zincblende has a fcc Bravais lattice with two atoms in the basis. The conventional unit cell is a cube with sides of a .

Sphalerite has been found as a pseudomorph, taking the crystal structure of galena, tetrahedrite, barite and calcite. Sphalerite can have Spinel Law twins, where the twin axis is [111].
