Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a zinc blende crystal structure.. 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. 3d il - 2BGMN2Y from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Diamond's cubic structure is in the Fd 3 m space group, which follows the face-centered cubic Bravais lattice.The lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motif of two tetrahedrally bonded atoms in each primitive cell, separated by 1 / 4 of the width of the unit cell in each dimension.

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. The third important structure for AB (binary) lattices is zinc blende (Figure 3D). It is based on the diamond structure, where every other atom is A or B. Many binary semiconductors have this structure, including those with one atom from the third (boron, aluminum, gallium [Ga], or indium [In]) and one from the fifth (nitrogen, phosphorus, arsenic [As], or antimony [Sb]) column of the periodic table (GaAs, InP, etc.). Most of the chalcogenides (O, S, Se, Te) of cadmium and zinc (CdTe, ZnSe Zinc blende: T+ (or T-) occupied; O, T-(or T-) empty Antifluorite: T+, T-occupied; O empty Unit cells are shown in Fig. 1.24, in oblique projection and as projections on the ab face. Formula A xXy, the coordination numbers (CNs) of A and X must be in the ratio of y:x. For rock salt and zinc blende, x = y and anions and cations have the same CN. Since zinc blende InN as well as corresponding wurtzite GaN and InN have similar electronic structures as zinc blende GaN, we expect that these materials will also reveal strong s-d coupling.

Here are the two most important crystal structures for semiconductors. They are often referred to by the historical names " Zinc blende " from the German "Zinkblende" = α -ZnS, a rather ubiquitous mineral. The name " Sphalerite " also comes form the German: "Sphalerit", which, as was the custom of the time, stems from the Greek "sphaleros" meaning treacherous or malicious because it is easy to confuse it with other minerals. The structure is closely related to the structure of diamond.
