GaN Wafers

Gallium nitride belongs to the third generation of semiconductor material with hexagonal wurtzite structure. It has the characteristics of large forbidden band width, high thermal conductivity, high temperature resistance, radiation resistance, acid and alkali resistance, high strength and high hardness. It has broad application potential and good market prospects in the fields of high-brightness blue, green, purple and white light diodes, blue and purple lasers, and anti-radiation, high-temperature and high-power microwave devices.


OST Photonics offer free-standing 2” and 4” GaN wafers for semiconductor industry. There are two types of GaN materials for you to choose from: N-type GaN and semi-insulating GaN. Customized GaN substrates and GaN epitaxial on sapphire substrate are also available upon requests.
