Description

Trimethylgallium (TMGa) is a highly reactive organometallic compound with the molecular formula C3H9Ga and CAS number 1445-79-0. This colorless, pyrophoric liquid is a critical precursor in metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE) processes for the production of advanced semiconductor materials, particularly gallium-containing compounds like GaN, GaAs, and Ga2O3. Packaged in high-purity stainless steel cylinders under inert gas to ensure stability, our TMGa is available in research and bulk quantities with guaranteed purity levels up to 99.9999% (6N), making it ideal for optoelectronic, photovoltaic, and microelectronic applications. Proper handling under argon or nitrogen atmosphere is required due to its air- and moisture-sensitive nature.

Application

Trimethylgallium serves as the primary gallium source in MOCVD growth of III-V semiconductor thin films for LED, laser diode, and high-frequency electronic devices. It is essential for manufacturing blue/green LEDs and laser diodes in nitride-based systems (GaN, InGaN). TMGa is also used in solar cell production (GaAs photovoltaics) and as a dopant precursor in advanced semiconductor fabrication.
