Wurtzite has a The structure of Zinc Blende 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. Highlight the ccp (face-centred) layers of S's The Zincblende structure (also written "zinc blende") is named after the mineral zincblende ( sphalerite ), one form of zinc sulfide (β-ZnS). As in the rock-salt structure, the two atom types form two interpenetrating face-centered cubic lattices. 2020-01-22 2020-09-30 Zinc blende or sphalerite. or Diamond structure.

/ Johansson, Jonas; Leshchenko, Egor D. In: Journal of Crystal Growth, Vol. 509, 03.2019, p. 118-123. Research output: Contribution to journal › Article In sphalerite the sulfur atoms are in a cubic close-packed array, with half of the tetrahedral sites occupied. This structure is a derivative of the diamond structure (see Fig. 9(b)) with each zinc atom surrounded by four sulfur atoms, and each sulfur atom surrounded by four zinc atoms in tetrahedral coordination. Zinc blende or sphalerite or Diamond structure.

As in the rock-salt structure, the two atom types form two interpenetrating face-centered cubic lattices. Zinc blende or sphalerite.

Sphalerite ((Zn, Fe) S) is a mineral and ore of zinc. It consists largely of zinc sulfide in crystalline form but contains variable iron; when iron content is high, sphalerite is an opaque black variety called marmatite. 属等轴晶系。.

Its existence with a structure essentially that of the zinc blende/wurtzite type has, however, now been discovered during an investigation 1 of the thermal decomposition of anhydrous nickel and Here we present the electronic structure and magnetic properties of binary compounds consisting of 3d transition metals and group V elements, viz., P, Sb, and As in the zinc-blende structure. We demonstrate that compounds of V, Cr, and Mn show half metallic behavior for appropriate lattice constants. Zinc blende and wurtzite are two forms of the mineral zinc sulphide, ZnS. The zinc blende structure derives from the fcc structure by stacking two fcc unit cells into one another, offset by a quarter of a spatial diagonal.

Each ion is 4-coordinate and has local tetrahedral geometry. Unlike wurtzite, zincblende is its own antitype -- you can switch the anion and cation positions in the cell and it doesn't matter (as in NaCl).
