Description and Uses

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.

Gallium(III) oxide is used in vacuum deposition. It is useful for making semiconductor devices, gallium-alumina catalyst, gas sensors, luminescent phosphors and dielectric coatings of solar cells. It shows potential for developing deep-ultraviolet TCOs (Transparent Conductive Oxides) and transparent electrodes for ultraviolet optoelectronic devices. Recent studies report that gallium oxide can be a strong contender for power electronic devices for example, in ultrahigh-voltage power switching applications. Films made of gallium oxide have gained commercial interest owing to their gas sensitive characteristics, and glasses made with gallium oxide are the preferred optical materials for use in advanced technologies.
