General description
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.
Application
Ga2O3 is widely used as a host material for the fabrication of electroluminescent devices. For example, europium-doped Ga2O3 thin films can be used as a light-emitting layer to fabricate an optically transparent electroluminescent device.
Due to its distinct optical and electrical properties like moderate conductivity and high laser damage threshold, Ga2O3 can be used in laser-driven electron accelerators, low-loss plasmonics, and Si-based dielectric laser accelerators.
It can also be used as an effective catalyst for the dehydrogenation of propane to propene.
