Gallium has three electrons in the outer shell, while arsenic lacks three. 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.

gallium arsenide. This makes it possible to separate the solar film from the original wafer. The wafer, now with a new stack of layers on top of it, is then bathed in hydrofluoric acid, which removes the aluminum arsenide layer, and leaves the original wafer intact. Then new, very thin layers of gallium arsenide film are separated from the wafer.
