Ga2O3 | Gallium Oxide basic knowledge

Last modified; May 5, 2010

Ga2O3 has a refractive index near 1.45 at 550 nm and transmits wavelengths below 300 nm. It is a popular wide-bandgap (up to 5 eV) material, characterized by good chemical and thermal stability. Ga2O3 thin films are used as luminescent phosphors as well as in high-temperature oxygen sensors and also as antireflection or passivation coatings on GaAs and other deep-UV-transparent oxides.
