In crystal: Covalent bonds. Gallium arsenide (GaAs) could be formed as an insulator by transferring three electrons from gallium to arsenic; however, this does not occur.
Gallium arsenide can produce laser light directly from electricity and is used in solar panels, including those on the Mars Exploration Rover. Gallium is a post-transition metal. Although it is a solid at room temperature Gallium is still so soft that you could cut it with a knife.
Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III - V direct bandgap 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.
Gallium arsenide (GaAs) as a MEMS substrate is a brittle, difficult- to-process material  and the machining of GaAs, by diamond saw or by conventional laser, releases arsenic into the atmosphere. This is in the form of either dust or as arsine gas.
GALLIUM ARSENIDE can react with steam, acids and acid fumes. Reacts with bases with evolution of hydrogen. Attacked by cold concentrated hydrochloric acid. Readily attacked by the halogens. The molten form attacks quartz. (NTP, 1992)
Gallium arsenide was not mutagenic in several strains of Salmonella typhimurium, with or without S9 metabolic activation enzymes, and no incr in the frequency of micronucleated erythrocytes was observed in peripheral blood of male and mice exposed to gallium arsenide by inhalation for 14 wk.
The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals.

(b) Determination of arsenic Until now, only measurements of arsenic have been used for monitoring exposure to gallium arsenide because occupational exposure limits for arsenic have been established
In this way, each of the arsenic and gallium atoms gets 8 electrons in its outermost shell. That means, there are covalent bonds between arsenic and gallium atoms, in a gallium arsenide compound. Although covalent bonds are stronger bonds, still it is possible to break the bonds, if sufficient energy is supplied externally.

Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide, GaInAs) is a ternary alloy (chemical compound) of indium arsenide (InAs) and gallium arsenide (GaAs).
Purity requirements for the raw materials used to produce gallium arsenide are stringent. For optoelectronic devices (light-emitting diodes (LEDs), laser diodes, photo-detectors, solar cells), the gallium and arsenic must be at least 99.9999% pure; for integrated circuits, a purity of 99.99999% is required. These purity levels are referred to ...
Gallium arsenide (chemical formula GaAs) is a semiconductor compound used in some diode s, field-effect transistor s (FETs), and integrated circuit s (ICs). The charge carriers, which are mostly electron s,move at high speed among the atom s.
2014-10-04· Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III-V direct bandgap semiconductor with a zinc blende crystal structure.
What is Gallium Arsenide? Gallium Arsenide (GaAs) is a compound semiconductor: a mixture of two elements Gallium (Ga) and Arsenic (As). The uses of Gallium Arsenide wafers are varied and include being used in some diodes, field-effect transistors (FETs) and integrated circuits (ICs).
An announcement from Motorola suggests that one long-awaited replacement may have arrived. Gallium arsenide (GaAs) has seemed a likely alternative to silicon ever since the earliest days of ...
Gallium trioxide and arsenic trioxide were also administered intratracheally to rats for comparison with gallium arsenide, since the former compounds are believed to be formed following dissolution of gallium arsenide. Gallium trioxide was observed to have little biologic activity, whereas arsenic trioxide produced some of the same qualitative effects as those noted when gallium arsenide was ...
Advantages of Gallium Arsenide over Silicon Low Temperature Coefficient – the temperature coefficient is a measure of performance (efficiency) loss versus temperature relative to 25C. Most solar materials such as Silicon (Si) lose a lot of efficiency when the temperature rises.
Gallium arsenide (GaAs) as a MEMS substrate is a brittle, difficult- to-process material  and the machining of GaAs, by diamond saw or by conventional laser, releases arsenic into the atmosphere.
