SPECTROSCOPY: Indium gallium arsenide detectors open up the near-IR
Scientific-grade CCDs exhibit high responsivity from the near-ultraviolet to the near-infrared (NIR) region of the spectrum—200 nm to 1.1 µm. At longer wavelengths, the photon energy is less than the silicon bandgap, and the silicon thus becomes transparent to the incident photons. However, III-V materials such as indium gallium arsenide ...

Gallium | Uses, Properties, & Facts | Britannica
In most of its compounds, gallium has an oxidation state of +3 and, in a few, +1 (for example, the oxide, Ga 2 O). There is no evidence for authentic compounds of gallium in its +2 state. The "dihalides," for example, contain Ga + and Ga 3+ in a one-to-one ratio. With the Group 15 (Va) elements nitrogen, phosphorus, arsenic, and antimony and the Group 13 elements aluminum and indium ...
