Indium arsenide, InAs, is a semiconductor composed of indium and arsenic. It has the appearance of grey cubic crystals with a melting point of 942 °C.[2]Indium arsenide is used for construction of infrared detectors, for the wavelength range of 1–3.8 µm. The detectors are usually photovoltaic photodiodes. Cryogenically cooled detectors have lower noise, but InAs detectors can be used in higher-power applications at room temperature as well. Indium arsenide is also used for making of diode lasers.


Indium arsenide is similar to gallium arsenide and is a direct bandgap material. Indium arsenide is sometimes used together with indium phosphide. Alloyed with gallium arsenide it forms indium gallium arsenide - a material with band gap dependent on In/Ga ratio, a method principally similar to alloying indium nitridewith gallium nitride to yield indium gallium nitride.
