12024-21-4 Usage

Gallium(III) oxide, also known as gallium sesquioxide, is a chemical compound with the formula Ga2O3. It is a white, odorless, and insoluble powder that has several uses. One of the most common uses of gallium(III) oxide is in the manufacturing of semiconductor devices, such as LEDs and power transistors. It is also used as a dielectric material in capacitors and in the production of specialty glass. Gallium(III) oxide is also an important catalyst in organic synthesis. Additionally, it has been studied for its potential use in gas sensors and as a material for solar cells.

Growth and characterization of gallium (III) oxide films

P Wu, YM Gao, R Kershaw, K Dwight, A Wold

, Materials Research Bulletin Volume 25, Issue 3, March 1990, Pages 357-363

A simple spray pyrolysis technique has been applied to the formation of dense, homogeneous gallium(III) oxide thin films on both silicon and silica substrates. The high quality of these films has been established by transmission electron microscopy, x-ray diffraction, optical spectra, and current-voltage measurements.
