Gallium(III) sulfide, Ga 2 S 3, is a compound of sulfur and gallium, that is a semiconductor that has applications in electronics and photonics. Structure.
Gallium(II) sulfide, GaS, is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga 2 4+ units which have a Ga-Ga distance of 248pm. [1] This layer structure is similar to GaTe, GaSe and InSe. [1]
4, can be used as a phosphor. [9] Gallium also forms sulfides in lower oxidation states, such as gallium(II) sulfide and the green gallium(I) sulfide, the latter of which is produced from the former by heating to 1000 °C under a stream of nitrogen. [7]: 94 The other binary chalcogenides, Ga 2 Se 3 and Ga 2 Te 3, have the zincblende structure.
Gallium and germanium are used in semiconductors, while germanium is also used in infrared technology, fibre optic cables and solar cells. Antimony is used in bullets and other weaponry, while ...
The Mars Exploration Rovers and several satellites use triple-junction gallium arsenide on germanium cells. [75] Gallium is also a component in photovoltaic compounds (such as copper indium gallium selenium sulfide Cu(In,Ga)(Se,S) 2) used in solar panels as a cost-efficient alternative to crystalline silicon. [76]
Gallium sulfide may refer to: Gallium(III) sulfide, Ga 2 S 3; Gallium(II) sulfide, GaS; Thiogallate cations containing gallium and sulfur This page was last edited on ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Gallium arsenide is an important semiconductor material for high-cost, high-efficiency solar cells and is used for single-crystalline thin-film solar cells and for multi-junction solar cells. [35] The first known operational use of GaAs solar cells in space was for the Venera 3 mission, launched in 1965.
