Gallium arsenide chemical compound Britannica

Gallium arsenide (GaAs) could be formed as an insulator by transferring three electrons from gallium to arsenic; however, this does not occur. Instead, the bonding is more covalent, and gallium arsenide is a covalent semiconductor. The outer shells of the gallium atoms contribute three electrons,. Read More.

Gallium Arsenide (GaAs) Wafer: Structure, Properties, Uses

Usually the gallium arsenide is deposited in a single thin layer on a small sheet, but at the University of Illinois, multiple layers of material have been deposited on the wafers, obtaining a higher yield. Multiple layers eliminate the limitations in the area of work, something very important in the case of solar cells, which require a wide
