Triethylgallium

Triethylgallium is a chemical compound used primarily in the production of semiconductor devices. It is a colorless liquid that is highly reactive with water and air.

Chemical Properties

Triethylgallium (TEG) is a organometallic compound with the formula Ga(C2H5)3. It is one of the simplest compounds of gallium. The compound is a colorless liquid at room temperature and is highly reactive with water and air. It is typically stored under an inert gas such as nitrogen or argon to prevent reaction with the atmosphere.

Uses

The primary use of triethylgallium is in the production of semiconductor devices. It is used as a precursor for the metalorganic chemical vapor deposition (MOCVD) of gallium-containing layers in the manufacture of light-emitting diodes (LEDs), laser diodes, and solar cells.

Safety

Due to its reactivity with water and air, triethylgallium is considered a hazardous substance. It can cause burns and serious eye damage. It is also harmful if inhaled, and may cause damage to organs through prolonged or repeated exposure.
