1Xiamen Powerway offers GaP wafer - gallium Phosphide which are grown by LEC(Liquid Encapsulated Czochralski) as epi-ready or mechanical grade with n type, p type or semi-insulating in different orientation(111)or(100).
Gallium phosphide (GaP), a phosphide of gallium, is a compound semiconductor material with an indirect band gap of 2.26eV(300K). The polycrystalline material has the appearance of pale orange pieces. Undoped single crystal wafers appear clear orange, but strongly doped wafers appear darker due to free-carrier absorption. It is odorless and insoluble in water.Sulfur or tellurium are used as dopants to produce n-type semiconductors. Zinc is used as a dopant for the p-type semiconductor.Gallium phosphide has applications in optical systems. Its refractive index is between 4.30 at 262 nm (UV), 3.45 at 550 nm (green) and 3.19 at 840 nm (IR).

Remark：
The Chinese government has announced new limits on the exportation of Gallium materials (such as GaAs, GaN, Ga2O3, GaP, InGaAs, and GaSb) and Germanium materials used to make semiconductor chips. Starting from August 1, 2023, exporting these materials is only allowed if we obtains a license from the Chinese Ministry of Commerce. Hope for your understanding and cooperation!

PAM-XIAMEN's Template Products consist of crystalline layers of gallium nitride (GaN), aluminum nitride (AlN),aluminum gallium nitride (AlGaN)and indium gallium nitride (InGaN), which are deposited on sapphire substrates, silicon carbide or silicon.PAM-XIAMEN's Template Products enable 20-50% shorter epitaxy cycle times and higher quality epitaxial1
Due to SiC physical and electronic properties,Silicon Carbide based device are well suitable for short wavelength optoelectronic, high temperature, radiation resistant, and high-power/high-frequency electronic devices,compared with Si and GaAs based device.
PAM-XIAMEN has established the manufacturing technology for freestanding (gallium nitride)GaN substrate wafer, which is for UHB-LED and LD. Grown by hydride vapour phase epitaxy (HVPE) technology,Our GaN substrate has low defect density.
