Gallium Oxide (Ga2O3)-Powder

Characteristic




Gallium(III) trioxide is an inorganic compound with the formula Ga2O3. It exists as several polymorphs, all of which are white, water-insoluble solids. Although no commercial applications exist, Ga2O3 is an intermediate in the purification of gallium, which is consumed almost exclusively as gallium arsenide.

Application




Gallium(III) oxide has been studied in the use of lasers, phosphors, and luminescent materials. It has also been used as an insulating barrier in tight junctions.Monoclinic β-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.




ε-Ga2O3 thin films deposited on sapphire show potential applications as solar-blind UV photodetector.




Thin Ga2O3 films are of commercial interest as gas sensitive materials and Ga2O3. Ellipsometry is a procedure that can be used to determine optical functions of the β-Ga2O3.




β-Ga2O3 is used in the production of Ga2O3-Al2O3 catalyst.
