Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio.

or hexagonal structure. Red lines are not showing bonds. Of course we see immediately that what many call Zinc blende or sphalerite is simply an fcc lattice with two atoms in the base: atom A at (0,0,0,) and atom B at (½, ½, ½). The zinc blende crystal structure is the structure named for the low-temperature phase of the ceramic ZnS. It is cubic with two interpenetrating FCC lattices ZnS – Zinc Blende; ZnS – Wurtzite; AB2 structures.

Thickness of HKL planes: 0 Å 10 Å Zincblende has a fcc Bravais lattice with two atoms in the basis. The conventional unit cell is a cube with sides of a. It has a hexagonal wurtzite structure similar to zinc oxide (ZnO) and lattice constants of a = 0.311 nm and c = 0.498 nm. The zinc blende structure has ccplfcc anions with cations in one set of tetrahedral sites, either T + or T - .The ZnS 4 tetrahedra are linked at their corners and each corner is common to four such tetrahedra.

(Althoughthe termzinc blende originatedin compoundssuchas ZnS, whichcould 2015-06-30 · In a recent study , we used a tight-binding theory, and calculated the band structure of the 2D rocksalt PbSe and zinc blende CdSe lattices with superimposed graphene-type honeycomb geometry. It became clear that the atomic lattice is of large importance, and that reported effective mass models only provide a rough indication of the real band structure. In zinc blende structure, (A) zinc ions occupy half of the tetrahedral sites (B) each Zn2+ ion is surrounded by six sulphide ions (C) each S2- ion is Zinc blende and wurtzite crystal structure formation in gold catalyzed InGaAs nanowires. / Johansson, Jonas; Leshchenko, Egor D.
