Trimethylgallium

Description:
Trimethylgallium (TMG) is an organometallic compound with the chemical formula Ga(CH₃)₃. It is characterized by its colorless, volatile liquid state at room temperature and has a distinctive sweet odor. TMG is highly reactive, particularly with moisture, and can decompose in the presence of water, releasing methane and forming gallium hydroxide. This compound is primarily used in the semiconductor industry, particularly in the production of gallium-based materials for applications such as metal-organic chemical vapor deposition (MOCVD) for thin films and quantum dots. Due to its reactivity, TMG must be handled under inert atmospheres to prevent hydrolysis and oxidation. It is also classified as a flammable substance, necessitating careful storage and handling practices. Additionally, TMG is known to exhibit toxicity, and appropriate safety measures should be taken to minimize exposure. Overall, trimethylgallium is a crucial precursor in advanced materials science, particularly in the development of optoelectronic devices.
