Zinc oxide (ZnO) is a good substrate for GaN thin film. It has large exciton binding energy of 60 meV and a bandwidth of 3.73 eV at room temperature, making it a luminescent material for ultraviolet and visible light. Due to the transparency in the visible region, the large electrome-chanical coupling coefficient and the properties of adsorption and desorption of gas molecules on its surface, it is expected to be used in energy limiters with high peak energy, GaN substrates with large size and high quality, and wireless communications which beyond 5GHz in the future, high electric field equipment, high temperature and high energy electronic devices etc.
CasCrysTech (CCT) provides high quality Zinc Oxide (ZnO) crystal which can be customized upon customer's requirements.
