InAs Indium Arsenide Single Crystal
To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.
Indium arsenide is used for construction of infrared detectors, for the wavelength range of 1 ~ 3.8 um. The detectors are usually photovoltaicphotodiodes. 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. Find indium arsenide for sale here today
