Specification
The Gallium phosphide (GaP), with the CAS registry number of 12063-98-8, is also known as Gallium phosphide. It belongs to the product categories of Electronic Materials; Materials Science; Micro/Nanoelectronics; Ceramics; Metal and Ceramic Science; Phosphide. Its EINECS registry number is 235-057-2. This chemical's molecular formula is GaP and molecular weight is 100.7. What's more, its IUPAC name is Gallanylidynephosphane. In addition, Gallium phosphide (GaP) is a compound semiconductor material with an indirect band gap of 2.26 eV. 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. Besides, it should be stored in airtight containers and placed in cool, ventilated, dry, clean storerooms. Gallium phosphide (GaP) can be prepared through high-pressure single-crystal furnace liquid seal technology and extension method. And it has applications in optical systems.
