21 Oct 2004 The Zincblende (B3) Structure · This is the cubic analog of the wurtzite lattice, i.e. the stacking of the ZnS dimers along the <111> direction is 

The Miller indices define a plane. There exists a vector that is perpendicular to this plane, e.g. in zinc blende blende materials, the [hkl] vector is always perpendicular to the (hkl) plane. However, for wurtzite, this is not necessarily true. The structure is closely related to the structure of diamond. The hexagonal analog is known as the wurtzite structure.

Zinc sulfide (ZnS) crystallizes in two different forms: Wurtzite and Zincblende.

We have reproduced these results quali-tatively in our LDA calculations in GaN and InN @Figs. 1~a!, 1~b!#4 via an all-electron full-potential linearized The space group of the Zincblende structure is called F 4 3m (in Hermann–Mauguin notation), or 216.

Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of anions. In both structures, the cations occupy one of the two types of tetrahedral holes present. In either structure, the nearest neighbor connections are similar, but the distances and angles to further neighbors differs.

Sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning “treacherous,” an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).

Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows.. GaAs is often used as a substrate material for the epitaxial Download this stock image: Gallium arsenide - GaAs - is a compound of the elements gallium and arsenic. It is a bandgap semiconductor with a zinc blende crystal structure.

Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS can be found. Summary: Zinc blend is a compound that comes in two forms: sphalerite and wurtzite. These are characterized by a 1:1 stoichiometric ratio of Zinc to Sulfur.

The crystal may be thought of as two interpenetrating fcc lattices, one for sulfur the other for zinc, with their origins displaced by one quarter of a body diagonal.

4 ii) Zinc blende ( sphalerite ) structure The zinc blende structure has ccplfcc anions with cations in one set of tetrahedral sites, either T+ or T-.The ZnS4 tetrahedra are linked at their corners and each corner is common to four such tetrahedra. The unit cell of zinc blende, Fig. 1.24(b), is shown again in Fig. 1.28(a), the teeth are zinc blende structure (Fig. 3d). The trans-formation from wurtzite to zinc blend occurs at root of the saw teeth (Fig.
