· GaCl3

Gallium chloride (GaCl3) is an inorganic salt compound classified as a ceramic material, consisting of gallium and chlorine ions. It functions primarily as a chemical precursor and dopant material in semiconductor and optoelectronic device fabrication, particularly in metal-organic chemical vapor deposition (MOCVD) processes for gallium nitride (GaN) and gallium arsenide (GaAs) growth. Engineers select GaCl3 for its high purity availability and effectiveness as a gallium source in controlled synthesis environments, though it requires careful handling due to its hygroscopic nature and corrosive properties.
