Question

In the zinc blende structure of ZnS, which operation can change the formula of zinc blende?

Answer 1

Thermodynamic stability changes the structure of zincbende from closet cubic packing to the hexagonal prism.

Explanation:

• Zincbelnde structure is characterized by either face-centered cubic structure (fcc) or closet packing structure i.e.(ccp).
• The face-centered or closet packing structure shows ABC pattern of packing in a three-dimension structure.
• As the temperature increase the density of crystal lattice decreases and vice versa.
• The Zincblende structure slowly changes to Wurtzite structure as it gains stability at thermodynamic equilibrium.
• Thus it becomes a hexagonal prism with 12 ions in the corner of the unit

Answer 2

Answer:-

Thermodynamic stability changes the structure of zincbende from closet cubic packing to the hexagonal prism.
