Gallium(III) oxide is an inorganic compound and ultra-wide-bandgap semiconductor with the formula Ga 2 O 3. It is actively studied for applications in power electronics, phosphors, and gas sensing. [5] [6] [7] The compound has several polymorphs, of which the monoclinic β-phase is the most stable.
Gallium(III) oxide reacts with fluorinating agents such as HF or F 2 to form gallium(III) fluoride, GaF 3. It is an ionic compound strongly insoluble in water. However, it dissolves in hydrofluoric acid, in which it forms an adduct with water, GaF 3 ·3H 2 O. Attempting to dehydrate this adduct forms GaF 2 OH·nH 2 O. The adduct reacts with ...

A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Gallium(III) chloride can be prepared from the elements by heating gallium metal in a stream of chlorine at 200 °C and purifying the product by sublimation under vacuum. [4] [5] 2 Ga + 3 Cl 2 → 2 GaCl 3. It can also be prepared from by heating gallium oxide with thionyl chloride: [6] Ga 2 O 3 + 3 SOCl 2 → 2 GaCl 3 + 3 SO 2
