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 .
At room temperature, gallium metal is not reactive with air and water because it forms a passive, protective oxide layer. At higher temperatures, however, it reacts with atmospheric oxygen to form gallium(III) oxide, Ga 2 O 3. [4] Reducing Ga 2 O 3 with elemental gallium in vacuum at 500 °C to 700 °C yields the dark brown gallium(I) oxide, Ga ...

A 2-inch diameter gallium oxide wafer is pictured at the Hangzhou International Science and Innovation Center of Zhejiang University in Hangzhou, Zhejiang province, China, on May 30, 2022.
Gallium(I) oxide is a brown-black diamagnetic solid which is resistant to further oxidation in dry air. It starts decomposing upon heating at temperatures above 500 °C, and the decomposition rate depends on the atmosphere (vacuum, inert gas, air).
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).
The spot price of gallium metal reached 1,975 yuan ($269.95) per kg on Oct. 18, up 18% since the start of July and up 8% since Aug. 1, d Chinese gallium prices hit 7-month high as demand improves ...
Gallium arsenide was first synthesized and studied by Victor Goldschmidt and his co-partner Donder Vwishuna in 1926 by passing arsenic vapors mixed with hydrogen over gallium(III) oxide at 600 °C. [ 7 ] [ 8 ] The semiconductor properties of GaAs and other III-V compounds were patented by Heinrich Welker at Siemens-Schuckert in 1951 [ 9 ] and ...
