What is gallium arsenide used for?
If you want to know what is gallium arsenide used for? then you should know what is gallium arsenide(GaAs) first. pls keep reading.
Gallium arsenide is an compound ,the formula of GaAs. Black gray solid, freezing point 1238 ℃(2,260 °F; 1,511 K). Molar mass: 144.645 g/mol. Solubility in water: insoluble.It is stable in air below 600 ℃ and isn't eroded by non oxidizing acid. Gallium arsenide is a crucial semiconductor material. It belongs to group Ⅲ - Ⅴ compound semiconductor. It belongs to sphalerite type lattice structure with lattice constant of 5.65×10-10 m. The band gap is 1.4 ev. it's a really important semiconductor material for high-cost, high-efficiency solar cells and is employed for single-crystalline thin film solar cells. Also , it for multi-junction solar cells.
Gallium arsenide, GaAs, is taken into account a possible substitute for silicon substrates, supported its potential for top speed applications where it can operate at high (1.9 GHz) frequencies using low power consumptions and high sensitivity. One reason that GaAs technology has not fulfilled its promise is that silicon technology has dramatically improved within the interim, particularly with improvements in speed, and has reduced the cost-effectiveness of pursuing GaAs development.
In semiconductor applications (transistors, photovoltaic cell s, lasers).Gallium arsenide is among the foremost widely used intermetallic semiconductor components (Harrison, 1986; McIntyr and Sherin, 1989). Gallium arsenide is additionally incorporated into light-emitting diodes and photovoltaic cells, while gallium alloys are used for amalgam as a coffee toxicity replacement for mercury.
Gallium arsenide is electroluminscent in infrared and is employed for telephone equipment, lasers, solar cell, and other electronic devices.
Gallium arsenide (GaAs) may be a III-V direct band gap semiconductor with a blende crystal structure. Gallium arsenide is employed within the manufacture of devices like microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows.
GaAs is usually used as a substrate material for the epitaxial growth of other III-V semiconductors, including indium gallium arsenide, aluminum gallium arsenide et al.
