How can you get Gallium phosphide

How can you get Gallium phosphide? Many people are unfamiliar with this item, and here's the introduction to it:

Gallium nitride is a kind of by Ⅲ elements gallium (Ga) and V elements phosphorus (P) synthetic Ⅲ - V compound semiconductor materials.

The gallium phosphating material produced in the production process industry can be divided into monocrystalline materials and epitaxial materials. The substrate monocrystals of industrial production are n-type semiconductor doped with sulfur and silicon. In the early stage of phosphating gallium monocrystalline, the liquid phase method was prepared under normal pressure. The method is then used to cover the direct pull of the liquid. Modern semiconductor industry to produce gallium nitride single crystal is in the high pressure synthesis furnace, by use of directional solidification technology, synthesis of gallium nitride polycrystalline properly processed into high pressure single crystal furnace for single crystal control. The gallium phosphating epitaxial material is obtained by means of liquid phase epitaxial or vapor phase epitaxial diffusion. Used to make light-emitting diodes. The liquid phase epitaxial material can produce red, yellow-green, pure green light emitting diodes, vapor phase epitaxy and diffused growth materials, which can make light-emitting diodes of yellow and yellow green light.
