Digalliumtrioxid

BeschreibungGallium(III) oxide (Ga2O3) is a wide band gap semiconductor that belongs to a family of transparent semiconducting oxides (TSO). It can form different polymorphs such as α-,β-, γ-, δ-, and ε-. Polycrystalline and nanocrystalline Ga2O3 can be prepared using several methods such as chemical vapor deposition, thermal vaporization, and sublimation, molecular beam epitaxy, melt growth, etc. It is widely used as a functional material in various applications including optoelectronics, chemical sensors, catalysis, semiconductor devices, field-effect transistors, and many others.

VerwendenIn semiconductors; gas sensing; catalysis. Nanostructures as blue and UV light emitters in optoelectronic device applications. Gallium(III) oxide has been reported in applications in lasers, phosphors, and luminescent materials. Monoclinic ß-Ga2O3 is used in gas sensors and luminescent phosphors and can be applied to dielectric coatings for solar cells. This stable oxide has also shown potential for deep-ultraviolet transparent conductive oxides, and transistor applications. Thin Ga2O3 films are of commercial interest as gas sensitive materials. ß-Gallium(III) oxide is used in the production of Ga2O3-Al2O3 catalyst.
