Description of GaP Wafer:

In semiconductors, gallium phosphide is a type III-V compound semiconductor that has a wide indirect band gallium phosphide (gap) Wafersgap. The crystal structure of this compound is the same as silicon. Its lattice constant is 0.545 nm and its electron and hole mobility are approximately 100 and 75 cm2/V-s, respectively. This material is odorless and insoluble in water. It has been used in the fabrication of many electronic devices, including CMOS and RF/V/A switches.

The main substrate material for LEDs is gallium phosphide, and it is transparent to red, yellow, and orange light. This characteristic makes gallium phosphide a superior choice for LEDs. These diodes are transparent to most light, so their use in electronic components depends on how brightly they emit light. However, there is a problem associated with this material. Although it is highly conductive, it does not emit enough light to be useful as a source of illumination.
