Description of GaAs Laser Epitaxial wafer

Gallium arsenide (GaAs) epitaxial wafer is an important semiconductor material, widely used in optoelectronics and high-frequency electronic devices.

It is grown on a gallium arsenide substrate through epitaxial growth technology and has excellent optoelectronic properties.

The direct bandgap characteristics of GaAs make it particularly prominent in light-emitting diodes (LEDs) and laser diodes (LDs), which can emit light efficiently and are suitable for optical communications and display technologies.

Compared with silicon, GaAs has higher electron mobility and can support faster switching speeds, which is particularly suitable for radio frequency (RF) and microwave devices.

In addition, GaAs epitaxial wafers show good stability and low noise characteristics in high-temperature environments, making them suitable for various high-power and high-frequency applications.

During the manufacturing process, commonly used epitaxial growth technologies include metal organic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE), which ensure the high quality and uniformity of the epitaxial layer.

After manufacturing, the GaAs epitaxial wafer undergoes processes such as etching, metallization and packaging to finally form high-performance electronic and optoelectronic devices.

With the advancement of science and technology, the application fields of GaAs epitaxial wafers continue to expand, especially in the fields of optical communications, solar cells and sensors, showing broad market prospects.
