Zinc sulfide (ZnS), a naturally occurring salt, is the main source of zinc. It has two common crystalline forms (polymorphs): Sphalerite (“zinc blende”), with a cubic crystal structure, is the form ...

Bulk InP has the zinc-blende crystal structure, because the free energy is slightly lower (ΔE = 6.8 meV per III–V atom pair) 18 for this structure than for InP with the wurtzite structure.

Zinc oxide is an inorganic compound with the chemical formula ZnO. It occurs as a white powder that is nearly insoluble in water. It crystallizes in two main forms, hexagonal wurtzite and cubic ...
