Beschreibung
Gallium(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.
Chemische Eigenschaften
white odourless powder
Verwenden
In 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.
Vorbereitung Methode
Gallium oxide is formed during the annealing or heating of
semiconductors containing gallium in the microelectronics
industry.
Allgemeine Beschreibung
Odorless fine white powder. Insoluble in water.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
GALLIUM(III) OXIDE may react with acids. Heating (to 1292° F) with magnesium causes a violent reduction to metallic slate.
Health Hazard
SYMPTOMS: Symptoms of exposure to GALLIUM(III) OXIDE include reduction of red blood cells and platelets, anemia, skin rash and nausea.
Brandgefahr
Flash point data for GALLIUM(III) OXIDE are not available; however, GALLIUM(III) OXIDE is probably combustible.
