Indium is a chemical compound of indium and arsenic. It is a semiconductor, and one of the III-V semiconductors.

Production and representation

Indium is formed at high temperatures of the elements:

Properties

Indium arsenide crystallizes in the sphalerite structure: arsenide forms a cubic close packing and indium occupied half of the tetrahedral holes. The band gap of the semiconductor is 0.35 eV.

Use

Such as other III -V semiconductor is indium application in the semiconductor industry. It is used for photodiodes in detectors for infrared radiation. Another field of application are laser diodes.

Safety

Indium is toxic and carcinogenic due to the presence of arsenic.
