Gallium arsenide single crystal detection

Gallium arsenide is an inorganic compound with the chemical formula GaAs. It is a black gray solid with a melting point of 1238 ℃. It can stably exist in the air below 600 ℃ and is not corroded by non oxidizing acids. Gallium arsenide is an important semiconductor material. It belongs to the III-V group compound semiconductor. Belongs to a sphalerite type lattice structure, with a lattice constant of 5.65 × 10-10m, with a bandgap width of 1.4 electron volts. On October 27, 2017, the International Agency for Cancer Research of the World Health Organization released a preliminary list of carcinogens for reference, with arsenic and inorganic arsenic compounds included in the Class 1 carcinogen list
