01 /Applications

Semiconductor Manufacturing

Gallium arsenide is a primary substrate material for producing high-performance integrated circuits (ICs) and transistors, particularly those requiring high operating frequencies. Its superior electronic properties enable faster signal processing compared to silicon.

Optoelectronics

It is widely used in the fabrication of light-emitting diodes (LEDs), laser diodes, and photodetectors. GaAs-based devices are essential for applications in telecommunications, optical storage, and solid-state lighting.

High-Frequency Electronics

GaAs is crucial for developing microwave and millimeter-wave devices, including power amplifiers and field-effect transistors (FETs). These components are vital for radar systems, satellite communications, and wireless infrastructure.

Solar Cells

Multi-junction solar cells utilising gallium arsenide exhibit high conversion efficiencies, making them suitable for specialised applications such as space power systems and concentrated photovoltaics.
