What are the GaAs Wafer Applications that Affect Our Lives?


Did you know that the fundamental nature of the bandgap of GaAs wafers allows them to be widely used in various optoelectronic devices? These devices include laser, solar cells, and LEDs.However, it’s important to note that the optoelectronic market is composed of segments that are usually extremely cost-conscious. For this reason, most of them have decided to focus on the fabrication of large diameter wafers to reduce the cost of production.

Military and Aerospace

Major military and aerospace applications use gallium arsenide wafers to ensure secure communications, efficient sensors, and radars. Thanks to the GaAs wafer’s ability to allow circuits to effectively perform at much higher frequencies, this semiconductor material has managed to pave its way into the commercial markets.Compared to germanium or silicon wafers, the bandgap width of these GaAs wafers is considerably greater. What’s more, the mobility of electrons is also significantly greater in this type of wafer. For this reason, GaAs wafers are usually used for the following:

  • Lasers
  • photoelectric cells
  • semiconductors
  • MESFET transistors
  • Tunneling diodes

It was only a matter of time after GaAs wafers progressed in federal programs that they could reach new markets that include personal communication systems, wireless local area networks, live satellite transmission, global positioning systems, and various forms of mobile communications.

Wireless Communication and High-speed Applications

Did you know that wireless and high-speed applications are dominated by semiconductors made from gallium arsenide? These include power amplifiers and switches for smart and feature phones, cellular phones, and WLAN-enabled devices. GaAs wafers also provide support for the infrastructure that supports these applications.Without gallium arsenide semiconductors, the following will not be able to connect to wireless broadband and Wi-Fi functionalities:

  • Tablets
  • Notebooks
  • personal computers
  • Cable TV,
  • Telecom
  • Datacoms
  • Direct broadcast satellite
  • Cloud
  • Social media and other modern technologies
