Gallium arsenide

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.

GaAs is often used as a substrate material for the epitaxial growth of other III-V semiconductors including: Indium gallium arsenide, aluminum gallium arsenide and others.

Preparation and chemistry

In the compound, gallium has a +3 oxidation state. Gallium arsenide single crystals can be prepared by three industrial processes:

Cloud gaming

Cloud gaming, sometimes called gaming on demand, is a type of online gaming. Currently there are two main types of cloud gaming: cloud gaming based on video streaming and cloud gaming based on file streaming. Cloud gaming aims to provide end users frictionless and direct play-ability of games across various devices.

History

In 2000, G-cluster demonstrated cloud gaming technology at E3. The original offering was cloud gaming service over Wi-Fi to handheld devices. Video game developer Crytek began research on a cloud gaming system in 2005 for Crysis, but halted development in 2007 to wait until the infrastructure and cable Internet providers were up for the task.OnLive officially launched in March 2010, and its game service began in June with the sale of its OnLive microconsole. On April 2, 2015, it was announced that Sony Computer Entertainment had acquired OnLive's patents, and OnLive closed its doors. In November, SFR launched a commercial cloud gaming service on IPTV in France, powered by G-cluster technology.
