Gallium(III) Selenide (Ga₂Se₃), also known as Gallium Triselenide, is a III–VI semiconductor compound composed of gallium and selenium. It is valued for its wide band gap, defectordered crystal structures, and strong optical response, making it useful across semiconductor, optoelectronic, and specialty chemical industries.
Highpurity Ga₂Se₃ is commonly used in semiconductor fabrication and photooptic applications, and it also serves as an intermediate in certain chemical, agricultural, and pharmaceutical processes where highpurity seleniumcontaining compounds are required.
In advanced electronics, highpurity Ga₂Se₃ is widely employed as a source material for Molecular Beam Epitaxy (MBE), supporting semiconductor research and the production of nextgeneration electronic and optoelectronic devices.
