Trimethylgallium, Ga(CH3)3, often abbreviated to TMG, is the preferred metalorganic source of gallium for metalorganic vapour phase epitaxy (MOVPE) of gallium-containing compound semiconductors, such as GaAs, GaN, GaP, GaSb, InGaAs, InGaN, AlGaInP, InGaP and AlInGaNP. Occupational safety and health is a cross-disciplinary area concerned with protecting the Safety, Health and welfare of people engaged in In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly Organometallic chemistry is the study of Chemical compounds containing bonds between Carbon and a Metal. Gallium (ˈgæliəm is a Chemical element that has the symbol Ga and Atomic number 31 Metalorganic vapour phase epitaxy (MOVPE is a Chemical vapour deposition method of epitaxial growth of materials especially Compound semiconductors from A Compound Semiconductor is a Semiconductor Compound composed of elements from two or more different groups of the Periodic table. Gallium arsenide ( GaAs) is a compound of two elements Gallium and Arsenic. Gallium nitride ( is a very hard material commonly used in bright LEDs since the 1990s Gallium phosphide () a Phosphide of Gallium, is a compound Semiconductor material with an indirect Band gap Gallium antimonide (GaSb is a semiconducting compound of Gallium and Antimony of the III-V family Indium gallium arsenide ( InGaAs) is a Semiconductor composed of Indium, Gallium and Arsenic. Indium gallium nitride ( InGaN, x1-x is a Semiconductor material made of a mix of Gallium nitride (GaN and Indium nitride Aluminium gallium indium phosphide (, also AlInGaP, InGaAlP, etc Indium gallium phosphide ( InGaP) is a Semiconductor composed of Indium, Gallium and Phosphorus.
TMG is a clear, colorless, pyrophoric liquid[1]. A pyrophoric substance will ignite spontaneously that is its Autoignition temperature is below Room temperature. Even the hydrocarbon solutions of TMG, when sufficiently saturated, are known to catch fire on exposure to air. TMG is known to react violently with water and other compounds that are capable of providing labile active hydrogen (i. Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 e. protons). The proton ( Greek πρῶτον / proton "first" is a Subatomic particle with an Electric charge of one positive Therefore, TMG needs to be handled with care and caution, e. g. stored in a cool, dry place at 0-25 ºC, under inert atmosphere, and ensuring that storage temperatures would not exceed 40 ºC to avoid deterioration. In English to be inert is to be in a state of doing little or nothing
